Abstract
- Heterochromatin in aging stem cells Analysis of human aging syndromes, such as Werner syndrome (WS), may lead to greater understanding of both premature and normal aging. Zhang et al. generated isogenic WS-specific human embryonic stem cell lines (see the Perspective by Brunauer and Kennedy). WS-mesenchymal stem cells displayed features characteristic of premature aging, including heterochromatin disorganization. WRN protein thus functions in the maintenance of heterochromatin, and heterochromatin alterations may represent a driving force of human aging. Science , this issue p. 1160 ; see also p. 1093
