Descrição

Expression of the two isoforms of cyclooxygenase enzyme, cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), by in vitro produced bovine embryos was examined. Cumulus-oocyte complexes were recovered from ovaries of slaughtered animals and subsequently in vitro matured and in vitro fertilized. Presumptive zygotes were cultured in serum containing medium (TCM 199+10% bovine superovulated oestrus serum) on a granulosa cell monolayer for 12 days.
