Differentiation of iPSCs into RPE cells. The differentiation process begins with colonies of iPSCs plated initially on Matrigel (a) and subsequently detached to be cultured as EBs in suspension, and in the presence of NIC for 2 weeks (b). c, d The EBs became pigmented following a 2-week exposure to Activin A, TGFB1, and FGF2. The pigmented regions in the EBs were mechanically dissected and plated in RPE medium (e) giving rise to a monolayer of pigmented cells with a cobblestone appearance that can be further purified and expanded (f). Scale bars: a, b, 20 μm; c, 50 μm; d, 10 μm; e, 100 μm; f, 50 μm
