Testis of Alligator mississippiensis at five months after hatching in parasaggital view stained with PAMS. A and B: Seminiferous tubules (S) lie within a robust tunica albuginea (TA) of PAMS-positive fibers bordering the coelom (*). Occasional fenestrations connect seminiferous tubules to the coelomic cavity (star). Tubule basement membranes (BM) and surrounding interstitial tissues show PAMS-positive fibers. Primary spermatocytes (PS); Round spermatids (RSt). Clusters of Leydig cells (Le) are interspersed within the interstitial tissues. C: Putative germ cells are occasionally observed on the coelomic side of the tunica (pGC). Scale bars = 100 um.
