Nuclear transfer of mouse follicular epithelial cells pretreated with spermine, protamine, or putrescine.

Abstract

The in vitro and in vivo developmental potential of nuclear transferred embryos receiving follicular epithelial cells pretreated with spermine (5 and 20 mM), protamine (0.25 and 25 mg/ml), or putrescine (1 and 100 microg/ml) at room and reduced temperatures was examined in the mouse. The pretreated donor cells were first fused with enucleated oocytes, and… (More)
