In vitro inhibition of oocyte nuclear maturation in the bovine.


Bovine follicular oocytes (N = 5991) were exposed to an analog of cyclic adenosine 3',5'-monophosphate (cAMP), dibutyryl cyclic AMP (db-cAMP) (2.5, 5, and 10 mM), the phosphodiesterase inhibitor isobutyl methyl xanthine (IBMX, 0.2 mM), or the purine, hypoxanthine (0.5, 1.0, 2.0 mM), and the nucleoside, adenosine (0.05, 0.1, 0.2 mM), for 6 or 21 h to assess… (More)
