Figure 1. Expression of the Mas receptor protein in the mouse retina at different developmental time points. Immunofluorescence detection of Mas receptor protein expression at (A) postnatal day 1 (P1), (B) P5, (C) P7, (D) P15, (E) P21, and (F) P60 in the C57BL/6J mouse retina. The nuclei were counterstained with 4',6-diamidino-2-phenylindole (DAPI). NBL=neuroblast layer; ONL=outer nuclear layer; OPL=outer plexiform layer; INL=inner nuclear layer; IPL=inner plexiform layer; RGC=retinal ganglion cell layer. Scale bar=50 μm.
