Expression Analysis of Gnrh1 and Gnrhr1 in Spermatogenic Cells of Rat

Figure 3

Localization of Gnrh1 and Gnrhr1 by in situ hybridization in rat testis during the stage of the spermatogenetic cycle ((a)–(f)). The blue staining indicates the positive cells; few of them, representative of the different cell types, are pointed out by white arrowhead, SPT ((a)–(f)); black arrow, peritubular myoid cells ((b), (c), (e), and (f)); SC, Sertoli cells. The insets are shown in 100x magnification. Scale bars: 20 μm. The results are representative of one of three assays.
