A protein has been added to blood cells that appears to make them young again—cue the speculation on whether this substance is, at long last, a way to reliably reverse some of the effects of aging.

According to New Scientist, researchers discovered that older mice had low levels of a protein called osteopontin, and that stem cells injected into the mice quickly aged. The reverse—putting old stem cells into a dish filled with osteopontin—appeared to rejuvenate them. The team behind the work say they are developing a drug that they hope could be used to, as one of the researchers put it, “make old blood young again,” and boost older people’s immune systems.

The thing is, the gap between a bit of primary research and a clinically effective drug is huge—especially in the anti-aging arena. Several years ago, scientists and the public alike were excited to learn that when an old mouse and a young mouse were surgically joined so that they shared a circulatory system, the old mouse showed many signs of growing young again. The secret to prolonging life, it seemed, was in youthful blood.
