The major focus of the Rafii laboratory is to isolate and characterize known and novel adhesion and membrane-bound cytokines expressed by endothelium that regulate proliferation and adhesion of hematopoietic stem cells and their progenitors. To this end, they have utilized expression cloning strategy using BMEC and FLEC cDNA libraries to screen for known and novel adhesion/homing receptor and membrane-bound cytokines that regulate proliferation of hematopoietic progenitors. In collaboration with Dr. R. Crystal, adenoviral vectors overexpressing cytokines and adhesion molecules are being used to examine their function in long-term CD34+ progenitor-endothelial coculture studies. Direct introduction of adenoviral vectors expressing stem cell active cytokines into hematopoietic microenvironment provides novel approaches for the treatment of acquired or congenital hematological disorders.
