In certain people with cancer or other serious diseases, transplants of healthy adult stem cells can be lifesaving. But donating blood-forming stem cells is a bit more complicated than giving blood. For example, stem-cell donors most often undergo five days of injections to build up enough of those vital cells in the blood for donation.

Wouldn’t it be great if we could find a way to make the donation process easier? Such improvements are now on the horizon.NIH-funded researchers recently found that, at least in mice, a single injection of two complementary treatments can generate enough stem cells in 15 minutes [1]. What’s more, stem cells harvested in this way have qualities that appear to increase the odds of transplant success.
