Figure 1From: Enhanced generation of retinal progenitor cells from human retinal pigment epithelial cells induced by amniotic fluidMicroscopic images of RPE cells. A, B: Deeply pigmented RPE progeny, at the first passage, with different morphologies that had recently attached to the plate surface. C, D: Elongated RPE cells at late passages; demonstrating the appearance of peripheral processes and loss of pigmentation after several passages. Magnification: 200.Back to article page
