Homologous feeder culture system can efficiently promote the proliferation of embryonic germ (EG) cells or embryonic stem (ES) cells while avoiding contamination by exogenous proteins and pathogens.

Because the science is hard and the politics mean, progress in understanding human pluripotent cells has been slow. Biologists first trumpeted their discoveries of human embryonic stem cells (hESCs) ...

Two genetic innovations could address major welfare and productivity issues within the broiler and layer industries.

Researchers at Newcastle University in England report they have coaxed the first human sperm cells from embryonic stem cells, in a remarkable demonstration of how quickly the field of stem-cell ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...

One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet ...

A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilized egg, starts to develop, ...
