PAUL(June 18, 2002)--Researchers at the University of Minnesota Stem Cell Institute (SCI) have found the first evidence that adult bone marrow-derived cells can differentiate in vitro and in vivo ...

In utero, the blastocyst implants and all three embryonic germ layers are formed during gastrulation. Somatic stem cells are present in many fetal and post-natal tissues.

Gastrulation is the formation of the three principal germ layers—endoderm, mesoderm and ectoderm. Understanding the formation of the basic body plan is not only important to reveal how the ...

(1) Embryoid Bodies: In a first example of a human 3D embryo model, researchers grew ESCs on non-adhesive dishes in media without a differentiation inhibitor or growth factor to develop into embryoid ...

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 ...

Pluripotency is defined as the ability of a stem cell to differentiate into any cell within the three germ layers (endoderm, mesoderm, and ectoderm). Embryonic stem cells can develop into any type ...

The researchers examined the effects of Huntington’s mutation at the earlier stage of gastrulation, during which the two-week-old embryo starts to form the three embryonic germ layers, from ...

The cells successfully generated well-differentiated teratomas, benign masses containing all three embryonic germ layers, including respiratory, bone, and neural tissue. ...

This includes theories of how mature cells from one embryonic layer can be directly reprogrammed to mature cells of another embryonic layer, even though the three germ layers are separated by ...

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 ...
