Recently researchers and ambitious start-ups have promoted the idea that young blood may be used to reverse the aging process. This idea has roots going back thousands of years of human history. A company is offering $8000 for an infusion of plasma from a young donor. But the FDA pushed back with a warning that there is little evidence to support the companies claim: (https://www.scientificamerican.com/article/fda-issues-warning-about-young-blood-transfusions/).
But what could be learned from the study of young blood versus ‘old blood’? Perhaps identifying differences in circulating stem cells, hormones, growth factors, anti-oxidants or other factors may be revealed that could advance our knowledge of the aging process. Or maybe removal of harmful factors from the old blood is the key to longevity?
Let us know what proof is needed to bolster the claim that young blood is benefiicial?
