Îmbătrânirea ar putea începe în măduva osoasă. Cercetătorii au descoperit cum celulele stem din sânge influențează întregul organism

Scientists have identified a mechanism linking aging blood stem cells to systemic aging signs. Research on mice shows that aged hematopoietic stem cells produce inflammatory immune cells affecting distant organs. The protein SIRT3 plays a crucial role in maintaining healthy stem cell function. Genetic modifications in stem cells led to improved physical and cognitive performance in mice. The findings suggest that blood stem cell aging impacts overall health, but caution is advised as results are preliminary and based on animal studies.
