Spermatogenesis

The stem cell population of the germinal cells lies on the basal lamina of the convoluted seminiferous tubules. These are Type A spermatogonia. These cells undergo mitosis: one of the daughter cells renew the stock of type A spermatogonia, the other becomes a type B spermatogonia. These divide and their daughter cells migrate towards the lumen.
