How close are we to identifying all of the signalling pathways that are involved in neural tube patterning? The fact that the same factors keep cropping up again and again might indicate that we are ...

In the human embryo, the neural tube forms between the 22nd and 26th day of pregnancy. Later, the brain and spinal cord will develop from this tube. The neural tube forms when an elongated flat tissue ...

Researchers have conducted a detailed study of neurulation -- how the neural tube forms during embryonic development. They conclude that this happens less actively than previously thought. This also ...

HOUSTON - (Oct. 17, 2019) - 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 ...

Neural crest cells have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development. But their capacity to form derivatives ...

Neural crest cells -- embryonic cells in vertebrates that travel throughout the body and generate many cell types -- have been thought to originate in the ectoderm, the outermost of the three germ ...

Neuroepithelial cells are stem cells that differentiate into neurons and glia, essential components of the human central nervous system, following the process of neurogenesis. Also known as ...
