Expression of Flk-1 RNA in retinal progenitor cells. A, Anti-BrdU immunocytochemical staining of a mouse P0 retina-labeled for 6 hr defines the proliferative zone.B, Flk-1 in situ hybridization of a P0 retina section reveals signals within the progenitor cell population and in newly differentiated amacrine cells. Black arrowheads in A and B indicate the ventricular surface of the retina. C,D, The same field of dissociated E15 retinal cells double-labeled for BrdU (C) and Flk-1 transcripts (D). Blue arrowheads indicate examples of costaining cells.
