Stress-related genes may be preferentially and rhythmically expressed as part of the circadian rhythms of older fruit flies, researchers report.

The surprising plasticity and trans-differentiation of transplanted stem-cells suggest that there may be a set of universal stem-cell genes that govern the undifferentiated proliferative state. In the July 3 Proceedings of the National Academy of Sciences, Terskikh et al. report attempts to define a common stem-cell gene profile by comparing hematopoietic and neural stem-cells (Proc Natl Acad Sci USA 2001, 98:7934-7939). They isolated hematopoietic stem cells (HSC) from mouse bone marrow and cre
