(A,B) Immature testis (M1), immunoperoxidase, and immunofluorescence. There is weak immunoreactivity of germ cells to Piscidin-1, especially spermatogonia A. There are a few scattered reactive immune cells. (C–F) Testis in early maturation (M2), immunoperoxidase and immunofluorescence. Spermatogonia B and spermatocytes appear positive for Piscidin-1, as do some Sertoli cells. Scattered immune cells appear strongly reactive to the antibody tested. Legend: SgA = spermatogonia A; SgB = spermatogonia B; SrC = Sertoli cells; SC = sperm cysts; and IC = immune cells.
