(a) Northern blot analysis of FasL expression in purified populations of rat and mouse germ cells. Results are representative of three experiments. (b) Expression of mRNA for FasL in adult rat testis by ISH analysis with antisense probe under dark-field illumination. The high density of silver grain indicates that the site of FasL expression is in the elongated spermatids. (c) ISH analysis with sense probe under dark-field illumination shows the probe specificity. (50× magnification)
