Usefulness of modified Medium RD as a chemically defined medium for in vitro maturation of bovine oocytes.

ABSTRACT:

Purpose

In the present study, I evaluated the usefulness of Medium RD, with mixed RPMI1640 and Dulbecco's modified Eagle's medium (1:1, v/v), as a chemically defined medium for in vitro maturation (IVM) of bovine oocytes.

Methods

In vitro maturation was performed in 10 mmol/L HEPES-buffered TCM199 (mTCM199), 10 mmol/L HEPES-buffered Medium RD (mRD), and mTCM199 supplemented with fetal bovine serum fraction (mTCM199 + FBS fraction) that served as control. Cumulus-oocyte complexes were matured for 24 hours in three different media supplemented with follicle-stimulating hormone, estradiol-17β, and polyvinylpyrrolidone. Nuclear maturation of oocytes, their developmental competence into blastocysts after in vitro fertilization (IVF) and mitochondrial distribution in oocytes were
