Recently, the CRISPR/Cas9 (CRISPR-associated protein 9 nuclease, UniProtKB/Swiss-Prot entry Q99ZW2) system from S. pyogenes has been adapted for inducing sequence-specific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation.</p>',

While the exact mechanism of tau aggregation is unknown, the accumulation of aggregates correlates with disease progression. Here we report a genome-wide CRISPR screen to identify modulators of endogenous tau protein for the first time. Primary screens performed in SH-SY5Y cells, identified positive and negative regulators of tau protein levels. Hit validation of the top 43 candidate genes was performed using Ngn2-induced human cortical excitatory neurons. Using this approach, genes and pathways involved in modulation of endogenous tau levels were identified, including chromatin modifying enzymes, neddylation and ubiquitin pathway members, and components of the mTOR pathway. TSC1, a critical component of the mTOR pathway, was further validated in vivo, demonstrating the relevance of this screening strategy. These findings may have implications for treating neurodegenerative diseases in the future.</p>',

			'description' => '<p>The discovery, characterization, and adaptation of the RNA-guided clustered regularly interspersed short palindromic repeat (CRISPR)-Cas9 system has greatly increased the ease with which genome and epigenome editing can be performed. Fusion of chromatin-modifying domains to the nuclease-deactivated form of Cas9 (dCas9) has enabled targeted gene activation or repression in both cultured cells and in vivo in animal models. However, delivery of the large dCas9 fusion proteins to target cell types and tissues is an obstacle to widespread adoption of these tools for in vivo studies. Here we describe the generation and validation of two conditional transgenic mouse lines for targeted gene regulation, Rosa26:LSL-dCas9-p300 for gene activation and Rosa26:LSL-dCas9-KRAB for gene repression. Using the dCas9p300 and dCas9KRAB transgenic mice we demonstrate activation or repression of genes in both the brain and liver in vivo, and T cells and fibroblasts ex vivo. We show gene regulation and targeted epigenetic modification with gRNAs targeting either transcriptional start sites (TSS) or distal enhancer elements, as well as corresponding changes to downstream phenotypes. These mouse lines are convenient and valuable tools for facile, temporally controlled, and tissue-restricted epigenome editing and manipulation of gene expression in vivo.</p>',

poised to translate the experience of stress into altered brain function
and pathological mood, though the cellular and molecular mechanisms of this
process are not fully understood. Here, we use a novel method of
circuit-specific gene editing to show that the transcription factor
ΔFosB drives projection-specific activity of ventral hippocampus
glutamatergic neurons causing behaviorally diverse responses to stress. We
establish molecular, cellular, and circuit-level mechanisms for depression-

gene expression profiling to uncover novel downstream targets as potential
sites of therapeutic intervention in depression.',

			'description' => '<p>Acute myeloid leukemia (AML) is a highly aggressive hematopoietic malignancy, defined by a series of genetic and epigenetic alterations, which result in deregulation of transcriptional networks. One understudied but important source of transcriptional regulators are transposable elements (TEs), which are widespread throughout the human genome. Aberrant usage of these sequences could therefore contribute to oncogenic transcriptional circuits. However, the regulatory influence of TEs and their links to disease pathogenesis remain unexplored in AML. Using epigenomic data from AML primary samples and leukemia cell lines, we identified six endogenous retrovirus (ERV) families with AML-associated enhancer chromatin signatures that are enriched in binding of key regulators of hematopoiesis and AML pathogenesis. Using both CRISPR-mediated locus-specific genetic editing and simultaneous epigenetic silencing of multiple ERVs, we demonstrate that ERV deregulation directly alters the expression of adjacent genes in AML. Strikingly, deletion or epigenetic silencing of an ERV-derived enhancer suppressed cell growth by inducing apoptosis in leukemia cell lines. Our work reveals that ERVs are a previously unappreciated source of AML enhancers that have the potential to play key roles in leukemogenesis. We suggest that ERV activation provides an additional layer of gene regulation in AML that may be exploited by cancer cells to help drive tumour heterogeneity and evolution.</p>',

We compared the efficacy of double-strand breaks (induced by CRISPR/Cas9), single-nicks, or double-nicks (induced by Cas9n) in mediating repair of a COL7A1 splice-site mutation in exon 3 by homologous recombination (HR). We accomplished remarkably high HR frequencies of 89% with double-nicking while at the same time kept unwanted repair outcomes, such as non-homologous end joining (NHEJ), at a minimum (11%). We also investigated the effects of subtle differences in repair template design on HR-rates and found that strategic template nicking can enhance COL7A1 editing efficiency. In RDEB patient keratinocytes, application of double-nicking led to restoration and subsequent secretion of type VII collagen at high efficiency. Comprehensive analysis of 25 putative off-target sites revealed no off-target activity for double-nicking, while usage of Cas9 resulted in 54% modified alleles at one site.

For understanding pluripotency and lineage differentiation mechanisms, a critical first step involves systematically cataloging essential genes (EGs) that are indispensable for hPSC fitness, defined as cell reproduction in this study. To map essential genetic determinants of hPSC fitness, we performed genome-scale loss-of-function screens in an inducible Cas9 H1 hPSC line cultured on feeder cells and laminin to identify EGs. Among these, we found FOXH1 and VENTX, genes that encode transcription factors previously implicated in stem cell biology, as well as an uncharacterized gene, C22orf43/DRICH1. hPSC EGs are substantially different from other human model cell&nbsp;lines, and EGs in hPSCs are highly context dependent with respect to different growth substrates. Our CRISPR screens establish parameters for&nbsp;genome-wide screens in hPSCs, which will facilitate the characterization of unappreciated genetic regulators of hPSC biology.</p>',

Here, we established a novel approach for improved cell cryopreservation using an mRNA-based dCas9-VP64 gene activation system for transient, yet highly e&plusmn;cient expression of epigenetic related genes in mammalian cells for repression of metabolic activity. Before freezing, mammalian cells were treated by dCas9-VP64- modi&macr;ed mRNA and guide RNAs for upregulation of histone deacetylase (HDAC), DNA methyltransferase (DNMT) and transcriptional co-repressor Sin3A genes. Cell viability, karyotype, pluripotency, and other cell speci&macr;c functions were analyzed during post-thaw culture. Using conventional cryopreservation protocols, we found improvement of viability in dCas9- VP64 pretreated cells (P &lt; 0:05) compared to untreated cells. Combined with dCas9-VP64 system, a reduced amount of cryoprotectant (5% DMSO) did not negatively a&reg;ect the post-thaw viability. Co-delivering chemically modi&macr;ed dCas9-VP64 mRNA with gRNAs is an e&plusmn;cient gene delivery method compared to DNA-based strategies, without the associated safety concerns.

However, human embryonic stem cells and induced pluripotent stem cells (iPSCs) are more difficult to transfect and less resilient to DNA damage than immortalized tumor cell lines. Here, an optimized protocol is described for genome engineering of human iPSCs using simple transient transfection of plasmids and/or single-stranded oligonucleotides without any further selection or enrichment steps. This protocol achieves transfection efficiencies &gt;60%, with gene disruption efficiencies of 1-25% and gene insertion/replacement efficiencies of 0.5-10%. Details are also provided for designing optimal sgRNA target sites and donor targeting vectors, cloning individual iPSCs by single-cell FACS sorting, and genotyping successfully edited cells.</span></p>',

Recently, the CRISPR/Cas9 (CRISPR-associated protein 9 nuclease, UniProtKB/Swiss-Prot entry Q99ZW2) system from S. pyogenes has been adapted for inducing sequence-specific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation.</p>',

While the exact mechanism of tau aggregation is unknown, the accumulation of aggregates correlates with disease progression. Here we report a genome-wide CRISPR screen to identify modulators of endogenous tau protein for the first time. Primary screens performed in SH-SY5Y cells, identified positive and negative regulators of tau protein levels. Hit validation of the top 43 candidate genes was performed using Ngn2-induced human cortical excitatory neurons. Using this approach, genes and pathways involved in modulation of endogenous tau levels were identified, including chromatin modifying enzymes, neddylation and ubiquitin pathway members, and components of the mTOR pathway. TSC1, a critical component of the mTOR pathway, was further validated in vivo, demonstrating the relevance of this screening strategy. These findings may have implications for treating neurodegenerative diseases in the future.</p>',

Fusion of chromatin-modifying domains to the nuclease-deactivated form of Cas9 (dCas9) has enabled targeted gene activation or repression in both cultured cells and in vivo in animal models. However, delivery of the large dCas9 fusion proteins to target cell types and tissues is an obstacle to widespread adoption of these tools for in vivo studies. Here we describe the generation and validation of two conditional transgenic mouse lines for targeted gene regulation, Rosa26:LSL-dCas9-p300 for gene activation and Rosa26:LSL-dCas9-KRAB for gene repression. Using the dCas9p300 and dCas9KRAB transgenic mice we demonstrate activation or repression of genes in both the brain and liver in vivo, and T cells and fibroblasts ex vivo. We show gene regulation and targeted epigenetic modification with gRNAs targeting either transcriptional start sites (TSS) or distal enhancer elements, as well as corresponding changes to downstream phenotypes. These mouse lines are convenient and valuable tools for facile, temporally controlled, and tissue-restricted epigenome editing and manipulation of gene expression in vivo.</p>',

poised to translate the experience of stress into altered brain function

			'description' => '<p>Acute myeloid leukemia (AML) is a highly aggressive hematopoietic malignancy, defined by a series of genetic and epigenetic alterations, which result in deregulation of transcriptional networks. One understudied but important source of transcriptional regulators are transposable elements (TEs), which are widespread throughout the human genome. Aberrant usage of these sequences could therefore contribute to oncogenic transcriptional circuits. However, the regulatory influence of TEs and their links to disease pathogenesis remain unexplored in AML. Using epigenomic data from AML primary samples and leukemia cell lines, we identified six endogenous retrovirus (ERV) families with AML-associated enhancer chromatin signatures that are enriched in binding of key regulators of hematopoiesis and AML pathogenesis. Using both CRISPR-mediated locus-specific genetic editing and simultaneous epigenetic silencing of multiple ERVs, we demonstrate that ERV deregulation directly alters the expression of adjacent genes in AML. Strikingly, deletion or epigenetic silencing of an ERV-derived enhancer suppressed cell growth by inducing apoptosis in leukemia cell lines. Our work reveals that ERVs are a previously unappreciated source of AML enhancers that have the potential to play key roles in leukemogenesis. We suggest that ERV activation provides an additional layer of gene regulation in AML that may be exploited by cancer cells to help drive tumour heterogeneity and evolution.</p>',

To map essential genetic determinants of hPSC fitness, we performed genome-scale loss-of-function screens in an inducible Cas9 H1 hPSC line cultured on feeder cells and laminin to identify EGs. Among these, we found FOXH1 and VENTX, genes that encode transcription factors previously implicated in stem cell biology, as well as an uncharacterized gene, C22orf43/DRICH1. hPSC EGs are substantially different from other human model cell&nbsp;lines, and EGs in hPSCs are highly context dependent with respect to different growth substrates.

Here, we established a novel approach for improved cell cryopreservation using an mRNA-based dCas9-VP64 gene activation system for transient, yet highly e&plusmn;cient expression of epigenetic related genes in mammalian cells for repression of metabolic activity. Before freezing, mammalian cells were treated by dCas9-VP64- modi&macr;ed mRNA and guide RNAs for upregulation of histone deacetylase (HDAC), DNA methyltransferase (DNMT) and transcriptional co-repressor Sin3A genes. Cell viability, karyotype, pluripotency, and other cell speci&macr;c functions were analyzed during post-thaw culture. Using conventional cryopreservation protocols, we found improvement of viability in dCas9- VP64 pretreated cells (P &lt; 0:05) compared to untreated cells. Combined with dCas9-VP64 system, a reduced amount of cryoprotectant (5% DMSO) did not negatively a&reg;ect the post-thaw viability.

<p><br />Chromatin immunoprecipitation (<b>ChIP</b>) is a technique to study the associations of proteins with the specific genomic regions in intact cells. One of the most important steps of this protocol is the immunoprecipitation of targeted protein using the antibody specifically recognizing it. The quality of antibodies used in ChIP is essential for the success of the experiment. Diagenode offers extensively validated ChIP-grade antibodies, confirmed for their specificity, and high level of performance in ChIP.

While the exact mechanism of tau aggregation is unknown, the accumulation of aggregates correlates with disease progression. Here we report a genome-wide CRISPR screen to identify modulators of endogenous tau protein for the first time. Primary screens performed in SH-SY5Y cells, identified positive and negative regulators of tau protein levels. Hit validation of the top 43 candidate genes was performed using Ngn2-induced human cortical excitatory neurons. Using this approach, genes and pathways involved in modulation of endogenous tau levels were identified, including chromatin modifying enzymes, neddylation and ubiquitin pathway members, and components of the mTOR pathway. TSC1, a critical component of the mTOR pathway, was further validated in vivo, demonstrating the relevance of this screening strategy. These findings may have implications for treating neurodegenerative diseases in the future.</p>',

Fusion of chromatin-modifying domains to the nuclease-deactivated form of Cas9 (dCas9) has enabled targeted gene activation or repression in both cultured cells and in vivo in animal models. However, delivery of the large dCas9 fusion proteins to target cell types and tissues is an obstacle to widespread adoption of these tools for in vivo studies. Here we describe the generation and validation of two conditional transgenic mouse lines for targeted gene regulation, Rosa26:LSL-dCas9-p300 for gene activation and Rosa26:LSL-dCas9-KRAB for gene repression. Using the dCas9p300 and dCas9KRAB transgenic mice we demonstrate activation or repression of genes in both the brain and liver in vivo, and T cells and fibroblasts ex vivo. We show gene regulation and targeted epigenetic modification with gRNAs targeting either transcriptional start sites (TSS) or distal enhancer elements, as well as corresponding changes to downstream phenotypes. These mouse lines are convenient and valuable tools for facile, temporally controlled, and tissue-restricted epigenome editing and manipulation of gene expression in vivo.</p>',

the stress-induced changes in brain circuit function and gene expression
underlying depression symptoms are not completely understood, hindering
development of novel treatments. Because of its projections to brain
regions regulating reward and anxiety, the ventral hippocampus is uniquely
poised to translate the experience of stress into altered brain function
and pathological mood, though the cellular and molecular mechanisms of this
process are not fully understood. Here, we use a novel method of
circuit-specific gene editing to show that the transcription factor
ΔFosB drives projection-specific activity of ventral hippocampus
glutamatergic neurons causing behaviorally diverse responses to stress. We
establish molecular, cellular, and circuit-level mechanisms for depression-
and anxiety-like behavior in response to stress and use circuit-specific
gene expression profiling to uncover novel downstream targets as potential
sites of therapeutic intervention in depression.',

			'description' => '<p>Acute myeloid leukemia (AML) is a highly aggressive hematopoietic malignancy, defined by a series of genetic and epigenetic alterations, which result in deregulation of transcriptional networks. One understudied but important source of transcriptional regulators are transposable elements (TEs), which are widespread throughout the human genome. Aberrant usage of these sequences could therefore contribute to oncogenic transcriptional circuits. However, the regulatory influence of TEs and their links to disease pathogenesis remain unexplored in AML. Using epigenomic data from AML primary samples and leukemia cell lines, we identified six endogenous retrovirus (ERV) families with AML-associated enhancer chromatin signatures that are enriched in binding of key regulators of hematopoiesis and AML pathogenesis. Using both CRISPR-mediated locus-specific genetic editing and simultaneous epigenetic silencing of multiple ERVs, we demonstrate that ERV deregulation directly alters the expression of adjacent genes in AML. Strikingly, deletion or epigenetic silencing of an ERV-derived enhancer suppressed cell growth by inducing apoptosis in leukemia cell lines. Our work reveals that ERVs are a previously unappreciated source of AML enhancers that have the potential to play key roles in leukemogenesis. We suggest that ERV activation provides an additional layer of gene regulation in AML that may be exploited by cancer cells to help drive tumour heterogeneity and evolution.</p>',

We compared the efficacy of double-strand breaks (induced by CRISPR/Cas9), single-nicks, or double-nicks (induced by Cas9n) in mediating repair of a COL7A1 splice-site mutation in exon 3 by homologous recombination (HR). We accomplished remarkably high HR frequencies of 89% with double-nicking while at the same time kept unwanted repair outcomes, such as non-homologous end joining (NHEJ), at a minimum (11%). We also investigated the effects of subtle differences in repair template design on HR-rates and found that strategic template nicking can enhance COL7A1 editing efficiency. In RDEB patient keratinocytes, application of double-nicking led to restoration and subsequent secretion of type VII collagen at high efficiency. Comprehensive analysis of 25 putative off-target sites revealed no off-target activity for double-nicking, while usage of Cas9 resulted in 54% modified alleles at one site.

For understanding pluripotency and lineage differentiation mechanisms, a critical first step involves systematically cataloging essential genes (EGs) that are indispensable for hPSC fitness, defined as cell reproduction in this study. To map essential genetic determinants of hPSC fitness, we performed genome-scale loss-of-function screens in an inducible Cas9 H1 hPSC line cultured on feeder cells and laminin to identify EGs. Among these, we found FOXH1 and VENTX, genes that encode transcription factors previously implicated in stem cell biology, as well as an uncharacterized gene, C22orf43/DRICH1. hPSC EGs are substantially different from other human model cell&nbsp;lines, and EGs in hPSCs are highly context dependent with respect to different growth substrates. Our CRISPR screens establish parameters for&nbsp;genome-wide screens in hPSCs, which will facilitate the characterization of unappreciated genetic regulators of hPSC biology.</p>',

Here, we established a novel approach for improved cell cryopreservation using an mRNA-based dCas9-VP64 gene activation system for transient, yet highly e&plusmn;cient expression of epigenetic related genes in mammalian cells for repression of metabolic activity. Before freezing, mammalian cells were treated by dCas9-VP64- modi&macr;ed mRNA and guide RNAs for upregulation of histone deacetylase (HDAC), DNA methyltransferase (DNMT) and transcriptional co-repressor Sin3A genes. Cell viability, karyotype, pluripotency, and other cell speci&macr;c functions were analyzed during post-thaw culture. Using conventional cryopreservation protocols, we found improvement of viability in dCas9- VP64 pretreated cells (P &lt; 0:05) compared to untreated cells. Combined with dCas9-VP64 system, a reduced amount of cryoprotectant (5% DMSO) did not negatively a&reg;ect the post-thaw viability. Co-delivering chemically modi&macr;ed dCas9-VP64 mRNA with gRNAs is an e&plusmn;cient gene delivery method compared to DNA-based strategies, without the associated safety concerns. This approach is a simple, yet e&reg;ective way to accelerate a wide array of cellular research and translational medical applications.</p>',

This protocol achieves transfection efficiencies &gt;60%, with gene disruption efficiencies of 1-25% and gene insertion/replacement efficiencies of 0.5-10%.

However, human embryonic stem cells and induced pluripotent stem cells (iPSCs) are more difficult to transfect and less resilient to DNA damage than immortalized tumor cell lines. Here, an optimized protocol is described for genome engineering of human iPSCs using simple transient transfection of plasmids and/or single-stranded oligonucleotides without any further selection or enrichment steps. This protocol achieves transfection efficiencies &gt;60%, with gene disruption efficiencies of 1-25% and gene insertion/replacement efficiencies of 0.5-10%. Details are also provided for designing optimal sgRNA target sites and donor targeting vectors, cloning individual iPSCs by single-cell FACS sorting, and genotyping successfully edited cells.</span></p>',

Recently, the CRISPR/Cas9 (CRISPR-associated protein 9 nuclease, UniProtKB/Swiss-Prot entry Q99ZW2) system from S. pyogenes has been adapted for inducing sequence-specific double stranded breaks and targeted genome editing. This system is unique and flexible due to its dependence on RNA as the moiety that targets the nuclease to a desired DNA sequence and can be used to induce indel mutations, specific sequence replacements or insertions and large deletions or genomic rearrangements at any desired location in the genome. In addition, Cas9 can also be used to mediate upregulation of specific endogenous genes or to alter histone modifications or DNA methylation.</p>',

While the exact mechanism of tau aggregation is unknown, the accumulation of aggregates correlates with disease progression. Here we report a genome-wide CRISPR screen to identify modulators of endogenous tau protein for the first time. Primary screens performed in SH-SY5Y cells, identified positive and negative regulators of tau protein levels. Hit validation of the top 43 candidate genes was performed using Ngn2-induced human cortical excitatory neurons. Using this approach, genes and pathways involved in modulation of endogenous tau levels were identified, including chromatin modifying enzymes, neddylation and ubiquitin pathway members, and components of the mTOR pathway. TSC1, a critical component of the mTOR pathway, was further validated in vivo, demonstrating the relevance of this screening strategy. These findings may have implications for treating neurodegenerative diseases in the future.</p>',

Fusion of chromatin-modifying domains to the nuclease-deactivated form of Cas9 (dCas9) has enabled targeted gene activation or repression in both cultured cells and in vivo in animal models. However, delivery of the large dCas9 fusion proteins to target cell types and tissues is an obstacle to widespread adoption of these tools for in vivo studies. Here we describe the generation and validation of two conditional transgenic mouse lines for targeted gene regulation, Rosa26:LSL-dCas9-p300 for gene activation and Rosa26:LSL-dCas9-KRAB for gene repression. Using the dCas9p300 and dCas9KRAB transgenic mice we demonstrate activation or repression of genes in both the brain and liver in vivo, and T cells and fibroblasts ex vivo. We show gene regulation and targeted epigenetic modification with gRNAs targeting either transcriptional start sites (TSS) or distal enhancer elements, as well as corresponding changes to downstream phenotypes. These mouse lines are convenient and valuable tools for facile, temporally controlled, and tissue-restricted epigenome editing and manipulation of gene expression in vivo.</p>',

			'description' => '<p>Acute myeloid leukemia (AML) is a highly aggressive hematopoietic malignancy, defined by a series of genetic and epigenetic alterations, which result in deregulation of transcriptional networks. One understudied but important source of transcriptional regulators are transposable elements (TEs), which are widespread throughout the human genome. Aberrant usage of these sequences could therefore contribute to oncogenic transcriptional circuits. However, the regulatory influence of TEs and their links to disease pathogenesis remain unexplored in AML. Using epigenomic data from AML primary samples and leukemia cell lines, we identified six endogenous retrovirus (ERV) families with AML-associated enhancer chromatin signatures that are enriched in binding of key regulators of hematopoiesis and AML pathogenesis. Using both CRISPR-mediated locus-specific genetic editing and simultaneous epigenetic silencing of multiple ERVs, we demonstrate that ERV deregulation directly alters the expression of adjacent genes in AML. Strikingly, deletion or epigenetic silencing of an ERV-derived enhancer suppressed cell growth by inducing apoptosis in leukemia cell lines. Our work reveals that ERVs are a previously unappreciated source of AML enhancers that have the potential to play key roles in leukemogenesis. We suggest that ERV activation provides an additional layer of gene regulation in AML that may be exploited by cancer cells to help drive tumour heterogeneity and evolution.</p>',

We compared the efficacy of double-strand breaks (induced by CRISPR/Cas9), single-nicks, or double-nicks (induced by Cas9n) in mediating repair of a COL7A1 splice-site mutation in exon 3 by homologous recombination (HR).

To map essential genetic determinants of hPSC fitness, we performed genome-scale loss-of-function screens in an inducible Cas9 H1 hPSC line cultured on feeder cells and laminin to identify EGs. Among these, we found FOXH1 and VENTX, genes that encode transcription factors previously implicated in stem cell biology, as well as an uncharacterized gene, C22orf43/DRICH1. hPSC EGs are substantially different from other human model cell&nbsp;lines, and EGs in hPSCs are highly context dependent with respect to different growth substrates.

Here, we established a novel approach for improved cell cryopreservation using an mRNA-based dCas9-VP64 gene activation system for transient, yet highly e&plusmn;cient expression of epigenetic related genes in mammalian cells for repression of metabolic activity. Before freezing, mammalian cells were treated by dCas9-VP64- modi&macr;ed mRNA and guide RNAs for upregulation of histone deacetylase (HDAC), DNA methyltransferase (DNMT) and transcriptional co-repressor Sin3A genes. Cell viability, karyotype, pluripotency, and other cell speci&macr;c functions were analyzed during post-thaw culture. Using conventional cryopreservation protocols, we found improvement of viability in dCas9- VP64 pretreated cells (P &lt; 0:05) compared to untreated cells. Combined with dCas9-VP64 system, a reduced amount of cryoprotectant (5% DMSO) did not negatively a&reg;ect the post-thaw viability.

However, human embryonic stem cells and induced pluripotent stem cells (iPSCs) are more difficult to transfect and less resilient to DNA damage than immortalized tumor cell lines. Here, an optimized protocol is described for genome engineering of human iPSCs using simple transient transfection of plasmids and/or single-stranded oligonucleotides without any further selection or enrichment steps. This protocol achieves transfection efficiencies &gt;60%, with gene disruption efficiencies of 1-25% and gene insertion/replacement efficiencies of 0.5-10%. Details are also provided for designing optimal sgRNA target sites and donor targeting vectors, cloning individual iPSCs by single-cell FACS sorting, and genotyping successfully edited cells.</span></p>',
