Abstract:that members of the FGF receptor (FGFR) family are expressed in the diencephalon (bordering this turn site) throughout the period of optic tract development, suggesting that FGF signalling in the neuroepithelium could maintain the pattern of guidance factors for axons in the developing optic tract. Furthermore, we found that exposing the developing optic tract and neuroepithelium to an FGFR inhibitor (SU5402) just prior to when RGC axons reach the turn site in the diencephalon has two effects: (1) RGC axons st… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
