突变研究在CRISPR基因组编辑时代得到了迅速发展。对人类诱导多能干细胞(IPSCs)中基因的精确操作使生物医学研究人员能够研究单个基因在发育过程中的生理功能。此外,这种应用于患者特定IPSCs的基因操作使疾病建模、药物筛选和治疗学的开发成为可能。尽管已经开发了各种基因组编辑方法来引入或消除人类IPSCs中的突变,但考虑到CRISPR编辑的潜在副作用的全面战略设计是必要的。在这里,我们提出了几种新颖而高效的策略来在人类ipscs中引入点突变、插入和缺失,包括循序渐进的实验方案。这些方法包括应用药物选择进行毫不费力的克隆筛选,以及产生野生型对照菌株和突变体。我们还提供了这些策略在人类IPSCs中应用的几个例子,并表明它们是高效的,可以应用于其他类型的细胞。
Mutagenesis studies have rapidly evolved in the era of CRISPR genome editing. Precise manipulation of genes in human induced pluripotent stem cells (iPSCs) allows biomedical researchers to study the physiological functions of individual genes during development. Furthermore, such genetic manipulation applied to patient-specific iPSCs allows disease modeling, drug screening and development of therapeutics. Although various genome-editing methods have been developed to introduce or remove mutations in human iPSCs, comprehensive strategic designs taking account of the potential side effects of CRISPR editing are needed. Here we present several novel and highly efficient strategies to introduce point mutations, insertions and deletions in human iPSCs, including step-by-step experimental protocols. These approaches involve the application of drug selection for effortless clone screening and the generation of a wild type control strain along with the mutant. We also present several examples of application of these strategies in human iPSCs and show that they are highly efficient and could be applied to other cell types.
