Figure 1. Differentiation of human pluripotent stem cells toward retinal pigment epithelium cells. A: A schematic representation of retinal pigment epithelium (RPE) cell differentiation during retinal development. B: Reverse transcription (RT)–PCR analysis of typical genes for retinal development expressed during putative RPE differentiation of the human embryonic stem cell (hESC) line Regea 08/023 and human induced pluripotent stem cell (hiPSC) line FiPS 5–7 at sequential time points on D7–D72.
