How blood can be rejuvenated
(PHYSorg.com Medicine & Health)

Our blood stem cells generate around a thousand billion new blood cells every day. But the blood stem cells` capacity to produce blood changes as we age. This leads to older people being more susceptible to anaemia, lowered immunity and a greater risk of developing certain kinds of blood cancer. Now for the first time, a research team at Lund University in Sweden has succeeded in rejuvenating blood stem cells with established reduced function in aging mice. The study is published in Nature Communications.
