Type of stem cell found to reside in transplanted lungs

...author Vibha N. Lama, M.D., M.S., and her research team found that the MSCs in lung transplant patients are not derived from bone marrow, but rather that they reside ?sometimes for many years ?in the lungs. The researchers also found that these cells have the capacity to differentiate into multiple connec...

Discovery could lead to better control of hemorrhagic fever viruses

... increases. Consistent with these findings, Choe's team found that New World arenaviruses infect cells more efficiently when iron levels are low, and that adding iron to cultured cells makes them less susceptible to infection. Choe notes that New World hemorrhagic fever outbreaks mostly occur in poor rura...
