Figure 3. mRNA expression levels of stemness and RPE-specific genes in senescent and young RPESCs. (A) qRT-PCR analysis of the expression levels of stemness genes in senescent (P16) and young (P3) RPESCs. (B) qRT-PCR analysis of the mRNA levels of RPE-specific genes in senescent and young RPESCs. Data are mean ± SD of 3 independent experiments. *P = from 0.026 to 0.036.
