Self-incompatibilty in gamete recognition: single self-recognizing determinants and multiple, non-self-recognizing ones function in the same individual.

abstract：:Prostaglandins could be involved in various aspects of final differentiation of ovarian follicles. Prostaglandins are generated by the cyclooxygenase (cox) pathway. Until now, the expression pattern of isoforms cox-1 and cox-2 of cyclooxygenase in bovine cumulus-oocyte complexes (COCs) was unknown. Using immunodetecti...
