Differential cytotoxic effects of mono-(2-ethylhexyl) phthalate on blastomere-derived embryonic stem cells and differentiating neurons.

27 Aug 2009 Potential applications of embryonic stem (ES) cells are not limited to regenerative medicine but can also include in vitro screening of various toxicants. In this study, we established mouse ES cell lines from isolated blastomeres of two-cell stage ... Read more...

Coplanar film electrodes facilitate bovine nuclear transfer cloning.

30 Jul 2009 Automated lab on chip systems offer increased throughput and reproducibility, but the implementation of microelectrodes presently relies on miniaturization of parallel plate electrodes that are time consuming and costly to fabricate. Electric field ... Read more...

The NK-2 class homeodomain factor CEH-51 and the T-box factor TBX-35 have overlapping function in C. elegans mesoderm development.

13 Jul 2009 The C. elegans MS blastomere, born at the 7-cell stage of embryogenesis, generates primarily mesodermal cell types, including pharynx cells, body muscles and coelomocytes. A presumptive null mutation in the T-box factor gene tbx-35, a target of the ... Read more...

Technical information about 'Blastomeres'

Definition: Undifferentiated cells resulting from cleavage of a fertilized egg (ZYGOTE). Inside the intact ZONA PELLUCIDA, each cleavage yields two blastomeres of about half size of the parent cell. Up to the 8-cell stage, all of the blastomeres are totipotent. The 16-cell MORULA contains outer cells and inner cells.
