Calf born to cow with transplanted genetic info

TOKYO, Japan - A male calf inheriting genetic information from two aged cows that had been transplanted into a 3-year-old cow's ovum was born late Feb. 19, opening the way for what scientists hope would be similar treatment of fertility among women past their child-bearing prime. Researchers said the baby calf, born at a farm operated by Iwate University's agricultural department, looked bigger than average and appeared normal.

    Old cow ova nuclei transplanted to young ovum, calf expected

    MORIOKA, Japan - A surrogate mother cow (in photo taken Feb. 19) in Shizukuishi, Iwate Prefecture, is expecting a calf inheriting genetic information from aged female cows. A joint clinic and university team involved in the project said the ova nuclei from the older cows were transplanted into a younger cow's ovum, whose nucleus had been removed, and that the fertilized eggs produced through in vitro fertilization of this ovum were then transplanted into four surrogate mother cows, two of which became pregnant.
