(4) Post-Implantation Embryo Models: Scientists differentiated PSCs (naïve or primed stage) into lineages representing the primitive endoderm and ... 7,8 (5) Gastruloids: To overcome limitations in ...

Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.

Researchers use these spatially organized colonies to study gene expression and the role of cell density in embryo development. (4) Post-Implantation Embryo Models: Scientists differentiated PSCs ...

Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in your body. They're called stem cells. The stem cells continue to divide by ...

Final growth of the ovum takes place here - 4 to 7 days. Each protruding mature ovum and ... respiratory and excretory exchange of material by diffusion between embryonic and maternal circulatory ...

These discoveries highlight a valuable contribution that bioelectricity provides during embryonic development. By advancing our knowledge of electrotaxis within a living animal, this research ...
