Effects of senescent secretory phenotype acquisition on human retinal pigment epithelial stem cells

Figure 5. Human p53 and p21 protein expression levels in senescent and young RPESCs. p53 and p21 protein expression levels (A) Western blot analysis (B) and densitometric analysis of blots. Data are mean ± SD of 3 independent experiments. *P = from 0.022 to 0.046. (C) Relative expression levels of mRNA related to p21 and (D) p53 genes in young (P3), pre-senescent (P11) and senescent (P16) RPESCs cells. Data are mean ± SD of 3 independent experiments. *P = from 0.031 to 0.044.
