Fig. 5From: Fibroblast growth factor-5 promotes spermatogonial stem cell proliferation via ERK and AKT activationExpression of FGF5 in the human testis of OA and SCOS patients. a RT-PCR showed the expression of FGF5, FGFR1, and FGFR2 in freshly isolated human Sertoli cells. ACTB was used as a loading control of total RNA. b Immunocytochemistry showed FGF5 expression in human Sertoli cells of OA and SCOS patients. c Western blot confirmed that expression of FGF5 was decreased at protein level in Sertoli cells from SCOS patients. d IHC revealed the location of FGF5 expression in the human testis (scale bar = 10 μm). Asterisk indicated the location of FGF5 expression in the human testicular sectionBack to article page
