Isolation and characterization of a haploid germ cell specific sperm associated antigen 9 (SPAG9) from the baboon.

abstract：:It has been reported that the MRL/MpJ mouse strain shows several unique phenotypes, including rapid wound healing, inherent collagen disease, heat shock-resistant spermatocytes, and metaphase-specific apoptosis (Msa) in the testis. In the present study, we found the genetic mutation associated with Msa by chromosomal ...
