Figure 6. Expression of potential FGF-related signaling molecules in photoreceptors of PN5 rat retina in vitro

Cultures of photoreceptors were immunolabeled with antibodies specific for PLCg1 (A, D), SOS1 (B, E), SOS2 (C, F), ERK1/2 (G, J), SH-PTP2 (H, K), and Shc (I, L) after 3 d in vitro. The FGF-related signaling molecules examined were all expressed in photoreceptors, but showed differences in labeling intensity and sub-cellular distribution (see text for details).
