Florian, group leader at IDIBELL and P-CMR[C] and project leader.<\/p>\n<p>Blood stem cells, precursors of all blood cell types, are carriers for many regeneration factors. These results show how the rejuvenation of these cells could represent an effective strategy to improve the aging of the whole organism since it seems that their stimulation could be enough to rejuvenate everything.<\/p>\n<p>&nbsp;<\/p>\n<h3>A drug to rejuvenate blood stem cells<\/h3>\n<p>The drug used in this study to rejuvenate stem cells is CASIN, an inhibitor of a Cdc42 protein. Results show that stem cell treatment with this inhibitor stimulates their regeneration and, consequently, their transplantation improves life expectancy in mice.<\/p>\n<p>The Cdc42 protein is involved in cell polarity and preserves symmetry during cell division. Its activity increases with age, and its inhibition, with great rejuvenating potential, can be achieved with a brief CASIN treatment in elderly mice.<\/p>\n<p>&nbsp;<\/p>\n<p>This work has been
