Regulating hematopoietic differentiation

Blood cells originate from a small pool of hematopoietic stem cells (HSCs) through a complex process of differentiation steps that are tightly regulated at the transcriptional level. Dissecting the mechanisms underlying this ...

The Yin and Yang of stem cell quiescence and proliferation

Not all adult stem cells are created equal. Some are busy regenerating worn out or damaged tissues, while their quieter brethren serve as a strategic back-up crew that only steps in when demand shoots up. Now, researchers ...

Researchers parse the origins of hematopoietic stem cells

Researchers at the University of California, San Diego School of Medicine have identified a gene and a novel signaling pathway, both critical for making the first hematopoietic stem cells (HSCs) in developing vertebrate embryos. ...

Stem cell discovery could lead to improved bone marrow transplants

Researchers at the University of California, Santa Cruz, have identified a key molecule for establishing blood stem cells in their niche within the bone marrow. The findings, reported in the January issue of Cell Stem Cell, ...

Adipose tissue produces cells involved in immune response

French researchers from CNRS and the Universite Paul Sabatier have demonstrated the existence, in adipose tissue, of stem cells similar to those found in bone marrow. These cells are capable of differentiating into mast cells, ...
