Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen
of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the
loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the
ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility
Note générale sur le champ d'application :
