Participation of the female pronucleus derived from the second polar body in full embryonic development of mice
1 Jul 1997
Abstract excerpt
The second polar body (2PB), extruded from metaphase II oocytes after fertilization or oocyte activation, has a haploid set of female chromosomes like its sister, the fertilized (activated) oocyte. In the present study, the female pronucleus of fertilized mouse oocytes (zygotes) was replaced with the 2PB nucleus from the same or different oocytes to examine the developmental potential of the 2PB nucleus.
