Genome Sequencing Analysis for iPSC

The genetic integrity of iPSCs is critical to their effectiveness as disease models and potential therapeutic use.Creative Bioarray is committed to providing high-throughput genomic sequencing analysis for iPSCs to meet the specific needs of our clients in iPSC characterization.


iPSC lines contain deleterious genetic mutations, which will greatly weaken the biomedical utility of iPSCs. Although iPSCs are functionally similar to ESCs, recent microarray studies have demonstrated that human iPSCs carry higher levels of DNA copy number variation than ESCs. The main reasons for this result include: (1) reprogramming involves the expression of known oncogenes and is enhanced by downregulating genes that promote genomic stability; (2) reprogramming involves global epigenetic remodeling, which may have mutagenicity or result in the activation of endogenous retroelements; (3) iPSC comes from differentiated cell types rather than early embryos, indicating that somatic mutations in donor cells may bring genetic diversity to these cell lines, which may be harmful.

A variety of experimental protocols for generating iPSC lines have been established. However, to avoid the risk of cancer or dysfunction caused by some genetic variation when using these cells for regenerative therapy intervention, the detailed characterization of genetic differences between donor and derived cells is still an area that needs to be actively developed to ensure validity and safety.
