| Abstrakt: | Objective: To evaluate the ability of bovine cumulus-granulosa cells to survive cryopreservation and subsequently support bovine embryo development during coculture. Design: In vitro-matured and -fertilized bovine embryos (two- to four-cell) were allotted randomly to one of three treatment groups: [1] control medium alone consisting of Medium 199 containing 10% fetal bovine serum and antibiotics, [2] cocultured on fresh bovine cumulus-granulosa cells in control medium, or [3] cocultured on frozen-thawed cumulus-granulosa cells in control medium. Embryo development was assessed on days 7 and 8 after IVF. Results: Coculture improved embryo development on days 7 and 8 compared with the control group. However, embryo development on days 7 and 8 did not differ among coculture groups. Conclusions: Frozen-thawed cumulus-granulosa cells enhance embryo development similar to fresh cells during in vitro coculture. |
