Reconstructive surgeon aims for rejection-free limb transplantation

But to date about two-dozen people around the world have received hand transplants. Thomas Tung, M.D., conducts research within this relatively unorthodox realm of surgery, investigating the use of therapy that could potentially allow the body to accept donor tissue without the use of immunosuppressive medication.

Drug can quickly mobilize an army of cells to repair injury

Red areas of the circled leg in the right image show increased blood flow due to angiogenic cells.To speed healing at sites of injury – such as heart muscle after a heart attack or brain tissue after a stroke – doctors would like to be able to hasten the formation of new blood vessels. One promising approach is to “mobilize” patients’ blood vessel-forming cells, called angiogenic cells, so these cells can reach the injured area. Recently, researchers at Washington University School of Medicine in St. Louis demonstrated that a drug called AMD3100 can mobilize angiogenic cells from bone marrow of human patients in a matter of hours.

St. Louis Cardinals slugger Pujols gets Babe Ruth test at Washington University

Daniel Stier / GQ, September 2006El Hombre vs. The BabeBaseball purists, especially those of Yankee allegiance, might argue that St. Louis Cardinals homerun-hitting superstar Albert Pujols is simply not in the same league as legendary New York Yankees slugger Babe Ruth. Science may never settle that argument, but researchers at Washington University in St. Louis can offer some sense of how Pujols stacks up to the Babe in terms of skills necessary to hit the long ball. Pujols visited WUSTL to take part in a series of lab tests similar to those conducted on Ruth in 1921.
