Abstract

We have studied the distribution of histochemically detectable alkaline phosphatase in cultures of seminiferous tubule fragments and of peritubular cells from prepubertal rats. The same material also was immunohistochemically evaluated for the presence of desmin-containing intermediate filaments. The comparative analysis of alkaline phosphatase and desmin positivity shows that alkaline phosphatase histochemistry selectively detects desmin-containing contractile cells in tubular and peritubular cell cultures. We propose alkaline phosphatase as a novel marker for myoid cells that can be of help in screening, defining, and eventually standardizing the exact composition of peritubular cell cultures, a model that is of increasing interest in the study of cellular interactions in the testis.
