Researchers have discovered that microRNAs play an important role in embryonic development. The study pinpoints two microRNA families that direct the allocation of cells into the three germ layers -- ...

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 ...

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 layers ...

A little-known lipid plays a big role in helping us grow from a hollow sphere of stem cells into human beings, researchers have found. They found that in the first few days of life, ceramide helps ...

Embryonic patterning involves the complex interplay of multiple signalling pathways triggering gene regulatory networks, which, in turn, drive cell-fate choices and progenitor cell differentiation.

How do cells turn into organs? During embryonic development, three germ layers form, known as the endoderm, the mesoderm, and the ectoderm. These germ layers give rise to different parts of the ...

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 ...

Sanford-Burnham researchers discover that microRNAs play an important role in germ layer formation—the process that determines which cells become which organs during embryonic development LA JOLLA, ...
