A germ layer is a primary layer of cells that forms during embryonic development. The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals that are sister ...

Scientists from Helmholtz Zentrum München are revising the current textbook knowledge about gastrulation, the formation of the basic body plan, during embryonic development. Their study in mice has ...

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal ...

Understanding of the molecular drivers of lineage diversification and tissue patterning during primary germ layer development requires in-depth knowledge of the dynamic molecular trajectories of cell ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...

A study published today (September 11) in Nature Ecology & Evolution suggests that instead of two distinct germ layers, cnidarians may indeed have three. The authors show that the mesendoderm of the ...

Lymphoma invasion exhibited a germ layer-dependent organotropism, characterized by distinct heterogeneity in oncogenic mutations and signaling pathways, migration orderings, and developmental ...

An undifferentiated cell found in a differentiated tissue that can renew itself and (with limitations) differentiate to yield the specialized cell types of the tissue from which it originated. A ...

How does the “body” take shape? The body of animals is highly complex, containing distinct regions that carry out specific functions. As the body forms during embryogenesis, three germ layers are ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...
