Shaping up: Controlling a stem cell's form can determine its fate

Academics / General Science : Science Daily

New research reinforces the idea that stem cells can be induced to develop into specific types of cells solely by controlling their shape. The results may be important to the design of materials to induce the regeneration of lost or...

New blood: Tracing the beginnings of hematopoietic stem cells

Academics / General Science : Science Codex

Hematopoietic stem cells (HSCs) give rise to all other blood cell types, but their development and how their fate is determined has long remained a mystery. In a paper published online this week in Nature, researchers at the Univers...

How dynamic changes in methylation can determine cell fate

Academics / General Science : Science Daily

Scientists have uncovered intriguing new evidence helping to explain how methylation -- an epigenetic process -- can help determine the ultimate fate of stem cells.

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

Academics / General Science : Science Codex

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

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...
