We identified previously that signaling through Fgf receptor 1 (Fgfr1) maintains forebrain expression (Yang et al., 2018). Fgfr1. This is in contrast to (expression at a key guidance point for retinal ganglion cell (RGC) axons in the mid-diencephalon. We find that expression in the forebrain is promoted by a distinct set of Fgfrs, Fgfr2-4, from […]
