germinal layer , auch: germinative layer

The mesoderm is one of the three germinal layers that appears in the third week of embryonic development, its formed through a process called gastrulation.

During the early development of a human, neural stem cells lie in the germinal layer of the developing brain, ventricular and subventricular zones.

Following the loss of the nail, the nail bed forms a germinal layer which hardens as the cells acquire keratin and becomes a new nail.

The principal site of damage is the germinal layer, and often the initial response is erythema (reddening) due to blood vessels congestion and edema.

Under normal conditions, the neurons forming a germinal layer around ventricles migrate to the surface of the brain and form the cerebral cortex and basal ganglia.

Ruedi's theory : The basal cells of germinal layer of skin proliferate under the influence of infection and lay down keratinising squamous epithelium.

Embryo development of the first month is all the processes in which the embryo develops from the fusion of both gametes until the development of the three germinal layers.

In addition to the three abovementioned treatments, there is currently research and studies looking at new treatment involving percutaneous thermal ablation (PTA) of the germinal layer in the cyst by means of a radiofrequency ablation device.

Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth.

These research lines have already been turned into tissues representative of the three germinal layers, including neural stem cells, nerve cells, liver/pancreas precursors, skeletal muscle, fat cells, bone cells and blood vessels Text of the Stem Cell Therapeutic and Research Act of 2005 (P.L. 109-129) [.
