...Limiting numbers [of stem cells] has been a problem in bone marrow transplants and in trying to expand their use,” said David Scadden, associate professor of medicine at HMS and one of the researchers involved with the study. “Getting more stem cells is key, or needing fewer transplants...
Scadden worked with Laura Calvi of the University of Rochester Medical School and Gregor Adams of the Massachusetts General Hospital Cancer Center. The project combined Scadden’s interest in the interaction between stem cells and other cells with Calvi’s research on the relationship between bone and bone marrow...

...researchers also said they plan to do further research on stem cells. They hope to find a way to increase the number of stem cells in umbilical cord blood, since there are currently too few of them to use them for bone marrow transplants in adults...
