Abstract:
Objective To study the migration capability of mouse preimplantation embryos in uteri.Methods Total(1?045) embryos from CD-1 mouse including fertilized oocytes,2-cell embryos,morula,blastocysts,tetraploid embryos and parthenogenetic embryos were transferred unilaterally(right uterus or oviduct) into pseudopregnant CD-1 recipient females. Results Forty-five pregnant recipients were obtained.Among 45 recipients,implanted embryos,the scope from 5 to 20,were found at right uterine horn in each pregnant recipient,but only 6 implanted embryos in left uterine horn of 6 pregnant recipients.Conclusion Mouse preimplantion embryos barely migrate and move in between two uterine horns,embryos transferred unilaterally also can not implante equaly in left and right uterine horns.
