Keeping stem cells from changing fates

Academics / General Science : Science Daily (5 years ago)

Researchers have determined why certain stem cells are able to stay stem cells. A recent study reveals that an enzyme that changes the way DNA is packaged in cells allows specific genes to be turned on and off, thereby preventing a ...

Stem Cells Made From Developing Sperm

Academics / General Science : Science Daily (6 years ago)

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists have identified key molecular players responsible for th...

Keeping Stem Cells From Changing Fates

Health : Medical News Today (5 years ago)

Johns Hopkins researchers have determined why certain stem cells are able to stay stem cells. The report in the June 4 issue of Cell Stem Cell reveals that an enzyme that changes the way DNA is packaged in cells allows specific gene...

Harvard scientists find cell fate switch that decides liver, or pancreas?

Academics / General Science : Science Codex (last year)

Harvard stem cell scientists have a new theory for how stem cells decide whether to become liver or pancreatic cells during development. A cell's fate, the researchers found, is determined by the nearby presence of prostaglandin E2,...

Determining a stem cell's fate: Biologists scour mouse genome for genes and markers that lead to T cells

Academics / General Science : Science Daily (3 years ago)

What happens to a stem cell at the molecular level that causes it to become one type of cell rather than another? In studies that mark a major step forward in our understanding of stem cells' fates, scientists have traced the stepwi...
