Thirty-five embryos either were unanalyzable or had no dividing blastomeres. |
Here, human or mouse embryonic stem cells, in vitro representatives of the totipotent inner cell mass blastomeres, are placed into culture. |
In a blastula showing complete segmentation the blastomeres of the upper hemisphere are the more finely subdivided. |
Cell lineage analyses, mainly conducted on annelidan. and molluscan embryos, suggested that the ultimate fates of blastomeres are tremendously conserved. |
In the first, we injected calcium green into one of the blastomeres in the developing fish. |
In the mammalian embryo, for instance, the first compaction of the blastomeres is under the influence of E-cadherin to produce the trophectoderm. |
