According the The Daily Beast, research study at Weill Cornell Medical College has found that aged stem cells in mice can be rejuvenated by transplanting young blood vessel cells, causing a boost in blood system function. Blood vessel cells are important for sustaining nearby stem cells and aiding organ regeneration. Aging leads to declining functioning of these cells, causing a decrease in the immune system’s ability to fight infection and an increase in emergence of blood related cancer. This treatment may potentially supplement the current standard treatments for cancer although more research is needed. Aside from the benefit of rejuvenating the old stem cells which can aide in an overall healthier immune system, this exciting discovery could potentially increase recovery time from cancer therapy side effects, including protecting organs from radiation therapy.
