PLAG1-expressing cells in adult mouse testis. (a) lacZ-positive cells (blue) in a representative testis section of a 5-week-old Plag1 knock-out animal, as determined by X-gal staining. (b,c) Expression of lacZ (blue; X-gal staining) was found mostly in germ cells and only occasionally (arrowhead) in Sertoli cells (brown, GATA4 immunostaining). (d) Wild-type negative control for X-gal staining, showing no blue signal.
