They also found the 2- to 4-cell embryos could not distribute chromosomes correctly during cell division, and would stop growing at these very early stages of development. "NKX1-2 belongs to a ...

Advocates counter that adult stem cells, useful as they may be for some diseases, have thus far proved incapable of producing the full range of cell types that embryonic stem cells can.

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 ...

They show that rather than exclusively providing energy to the cell, glycolysis is able to control, at different stages of early embryonic development, cell fate decisions and the end-state appearance ...

Glycolysis is an ancient metabolic activity. It consists of a set of reactions that convert glucose into energy. This central ...

Early embryonic cell polarity and lineage differentiation ... acting via PRA/FK506 binding protein-4, and oestrogen signalling via ERα. An auto-induction loop of HB-EGF expression, which acts ...

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 ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development.
