Generation of GADD45A gene knockout human embryonic stem cell line using CRISPR/Cas9.

GADD45A is a DNA damage and stressful growth arrest inducible protein, also it is shown to a be tumor suppressor gene and a chromatin relaxer associated with opening chromatin during the somatic reprogramming. However, its role in human embryonic stem cells and human embryonic stem cell modeled development has been merely documented. To illustrate the function of GADD45A in the human embryonic stem cell biology, we reported a GADD45A knockout human embryonic stem cell line by CRISPR/Cas9 mediated gene targeting. This cell line displayed normal karyotype, pluripotent stem cell marker expression and differentiation potential both in vivo and vitro.
