Additional Study Information: The purpose of this study is to study the safety and feasibility of giving intestinal transplant patients CD34+ stem cells (the cells that make all the types of blood cells) obtained from their organ donor's bonemarrow as an IV infusion post-transplant. Researchers will be looking to see whether this CD34+ cell infusion might help control rejection of the new organ while reducing the risk of infection and disease associated with transplant medications. If you have any questions regarding this study, please contact the Transplant Clinical Research Center (TCRC).
