During embryonic development, the entire nervous system, the skin and the sensory organs emerge from a single sheet of cells known as the ectoderm. While there have been extensive studies of how this ...

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...

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

The entire inner ear and the neurons that innervate it derive from a simple piece of embryonic ectoderm next to the hindbrain called the otic placode. This ectoderm thickens, invaginates and folds up ...

An unexpected observation has led researchers at the Weizmann Institute of Science to challenge a 200-year-old doctrine regarding the embryonic origins of the pituitary gland. Situated at the base of ...

A cell aggregation of human pluripotent stem cells and amniotic ectoderm cells generated by the published culture method and mimicking the gastrulation event in human embryos. Gray: nuclei, Cyan: ...
