The physical forces that drive morphogenesis are not well characterized in vivo, especially among vertebrates. In the early limb bud, dorsal and ventral ectoderm converge to form the apical ectodermal ...

The ectoderm is the outermost layer of cells in very early vertebrate and insect embryos. It is one of the three primary germ cell layers and gives rise to the epidermis and nervous system. Corn ...

Bioscientists develop a method to observe patterns of early embryonic development, during which ectodermal cells diverge toward their fates as skin, organs and the nervous system. During embryonic ...

Many birth defects and spontaneous abortions occur during the embryonic development stage known as neurulation, yet we have very little insight into how this critical developmental process unfolds in ...

Sonic hedgehog is at work in mice limb buds in what is known as the ectoderm, the cell layer that gives rise to skin, researchers discovered. Finding Sonic hedgehog here is akin to discovering that ...

The team observed the emergence of the three-dimensional hematoids under a microscope in the lab. After just a few days these ...

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 ...

Annales Zoologici Fennici is an established, international, peer-reviewed journal, open to all scientists, appearing in six-number yearly volumes (until 2002 quarterly). It was founded in 1964 by ...

Both brain and skin arise from the ectoderm. A study found that psychosis patients with skin issues face higher depression ...
