Studies on the Transfer of Fertilized Mouse Eggs to Uterine Foster-mothers Ii. the Effect of Transferring Large Numbers of Eggs
INTRODUCTION In the previous paper of this series (McLaren & Michie, 1956) we described an experiment in which fertilized mouse eggs were transferred to the left uterine horn of recipient foster-mothers which were themselves pregnant with eggs of their own. Over the range tested (0-18 eggs), as the number of fertilized eggs transferred to the recipient female was increased, the number of embryo...
متن کاملViability and growth of mouse embryos after in vitro culture and fusion
About 80 % of 8-cell mouse eggs developed to the blastocyst stage in culture, whether the zona pellucida was left intact, or removed with pronase (pre-incubated and dialysed) and the eggs then cultured singly or as fused pairs. When pronase was used without prior incubation and dialysis, the success rate was reduced to 50 %. After transfer to uterine foster-mothers, 20-30 % of apparently normal...
