More On Cell Therapy By Cytokine

Randall Parker of FuturePundit has comments on the recent Italian demonstration of regenerative medicine by biochemical messaging: "Mind you, this is a news report on only 8 patients and not a journal article with a larger number of patients with controls and a detailed comparison of outcomes. Still, the approach is at least plausible. ... The technique might work less well in the really old because stem cell reservoirs in older people are aged and do not divide as quickly. However, one study found that elements in the blood of the old mice caused their stem cells to grow less rapidly. So it isn't so much that the stem cells are old but that they are getting signals telling them not to grow. Perhaps cytokines or other compounds can override those suppressor signals. So Marra's approach might work even for old folks."
