Proliferation deficits and gene expression dysregulation in Down's syndrome (Ts1Cje) neural progenitor cells cultured from neurospheres.

30 Oct 2009 Down's syndrome neurophenotypes are characterized by mental retardation and a decreased brain volume. To identify whether deficits in proliferation could be responsible for this phenotype, neural progenitor cells were isolated from the developing ... Read more...

Aging epidermis is maintained by changes in transit-amplifying cell kinetics, not stem cell kinetics.

30 Oct 2009 It has been assumed that the slow rate of healing in aging epidermis is due to slowing of the epidermal stem cell proliferative rate. In this issue, Charruyer et al. report that this may not be the case. Using a long-term repopulating model, they ... Read more...

Stem cell biology meets systems biology.

30 Oct 2009 Stem cells and their descendents are the building blocks of life. How stem cell populations guarantee their maintenance and/or self-renewal, and how individual stem cells decide to transit from one cell stage to another to generate different cell ... Read more...
