-cylinder like structure of an early mammal embryo decides what it will grow into-e.g.the heart,the gut or the brain,all of which will comprise the prospective animal body.But how does an embryonic tissue proge
How do stem cells differentiate during embryonic development? How is embryonic growth different from cell differentiation? How do master regulatory genes function in cell differentiation? How are somatic stem cells different from embryonic stem cells? How are embryonic stem cells different from somatic ...
Why would someone want to do that? Once a mother gives birth, the umbilical cord and remaining blood are often discarded. However, this blood also contains stem cells from the fetus. Umbilical cord blood can be harvested and the embryonic stem cells grown in culture. Unlike embryonic stem ...
Embryonic Stem Cells (ESCs): These pluripotent cells can differentiate into any cell type but involve ethical considerations due to their derivation from early-stage embryos Induced Pluripotent Stem Cells (iPSCs): These are adult cells reprogrammed to an embryonic stem cell-like state. iPSCs can ...
The neural crest cells that colonize the gut migrate further than other embryonic cells because the gut is growing as the cells migrate [18, 19]. The migration of ENCCs exhibits two important differences from neural crest cell populations that have been examined in detail previously. First, not...
On the other hand, there is a further type of stem cells present in the adult body, with the potential to develop (differentiate) into cells of all three embryonic germ lay- ers (ectoderm, mesoderm, endoderm) [1, 2, 6]. These cells, which are termed vascular associated pluripotent stem...
Neural crest cells are a transient migratory embryonic cell population. Previous imaging studies of cranial neural crest cells inXenopusand chick embryos have revealed the organization of the cells as they migrate, the rules guiding their behavior and some of the molecular bases of the interactions ...

[They] do not look different, and probably do not even behave differently. Has the controversy over embryonic stem cells impacted your work with nonembryonic stem cells? Not necessarily, because I think that scientists should be open and should not take into account the controversy. My point...
Without the discovery of stem cells, this process might not have been able to give parents the children they have always wanted ("Stem cells: What they are and what they do"). However, this is causing some controversy in today's society. Embryonic stem cells are obtained from embryos not...
