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.
PLCζ is compartmentalized as part of the acrosome early in human spermiogenesis and is secreted during sperm maturation in the epididymis. No evidence was found that PLCζ is incorporated into the detergent-resistant perinuclear theca fraction where sperm-borne oocyte activating factor (SOAF) resides.
- 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).
