<p>Bone marrow transplants, which involve transplanting healthy blood stem cells, offer the best treatment for many types of cancers, blood disorders and immune diseases. Even though 22,000 of these procedures are performed each year in the US, much remains to be understood about how they work.<\/p>\n<p>In a series of experiments, scientists learned that when transplanted into an\u00a0irradiated mouse, only a very small minority of the stem cells produce blood and immune cells, while many other stem cells become dormant and do nothing. In addition, post-radiation, this handful of\u00a0\u201csuper producer\u201d stem cells also become biased towards producing only certain types of immune cells. However, the overall blood and immune system, still tends to remain balanced.<\/p>\n<p>In mice that had not undergone radiation, all stem cells contributed equally to the blood and immune systems, with the exception of T cells, suggesting that the preconditioning regimen used to ensure successful transplantation is the source of the abnormal cell behavior.\u00a0<\/p>\n<p>Additional co-authors include: Agnieszka Czechowicz and Jun Seita from Stanford; and Du Jiang from USC.<\/p>\n<p>This research was supported by federal funding from the National Institutes of Health (grants R01-CA86065, U01-HL099999, K99\/R00-HL113104, R01-HL135292, R01-HL138225, and P30-CA014089).
