Human Spermatozoa Phospholipase C zeta Localization

Developmental localization of PLCζ in human (B, C) testes utilizing anti-hmPLCζ antibody. In human, there are six stages (I–VI) of the cycle of the seminiferous epithelium.

  • B - (stage II) PLCζ accumulates over the acrosomic vesicle (AV) of step 2 spermatids. Little immunoreactivity is found elsewhere in the epithelium and the elongated spermatids (arrowheads) appear unreactive.
  • C - (stage IV) step 4 spermatids the fully formed acrosome is intensely labeled (arrows).
