Description
We investigated roles of KRAS on stemness maintenance and differentiation propensity in the context of induced pluripotent stem cells (iPSCs) using isogenic KRAS mutant (G13C/WT) and wild-type (WT/WT) iPSCs from the same RAS-associated autoimmune lymphoproliferative syndrome-like disease (RALD) patients. RNA-seq analysis was conducted to compare gene expression profiles of WT/WT and G13C/WT iPS cells after in vitro differentiation. We found some differences of gene expression profiles regarding stemness and linage markers in the two genotypes. Overall design: To investigate the changes of stemness and linage markers between KRAS mutant and wild-type iPSCs after differentiation, the iPSCs were differentiated for 16 days . Two clones were used for each genotype (WT/WT and G13C/WT) before and after differentiation, resulting in total 8 conditions.
