Thus, they could determine the contribution of each cell to the development of two early structures: the trophectoderm (TE) that becomes the placenta and the inner cell mass (ICM) that eventually ...

The cells that reside in the inner cell mass of the early embryo, called the blastocyst, are pluripotent, and can develop into all cell types in the body. During embryonic development, the pluripotent ...

ES cells were originally derived from the inner cell mass (ICM) or epiblast of mouse ... the embryonic tissue is sufficient for the normal development to the adult stage. Using this assay, several ...

The blastocyst stage is characterized by the presence of a blastocyst cavity, outer cell mass and inner cell mass. Embryonic stem cells are derived from the inner cell mass of the blastocyst.

Researchers at Karolinska Institutet have developed a method that shows how the nervous system and sensory organs are formed in an embryo.

A breakthrough in imaging technology promises to transform our understanding of the inner workings of living cells, and ...
