Research Interests

Dr. Tillman's translational laboratory focuses in two primary research areas. His principal research direction is to develop novel therapies for vascular graft failure resulting from graft stenosis, which is a major cause of limb loss and mortality among vascular and dialysis patients, respectively. To date, local therapies have not been effective in control of this disease process. Several lines of evidence suggest involvement of circulating bone marrow derived progenitors in the formation of the hallmark intimal lesions of vascular graft failure. A novel progenitor depletion approach is being applied to examine and prevent the role of progenitor cells in vascular graft failure. As an extension of this potential new systemic paradigm of graft failure, the laboratory also applies neutralizing immunotherapy approaches to prevent recruitment of these cells to sites of vascular interventions.

A second and continued focus of the laboratory includes the development of bioreactor conditioned, tissue engineered grafts for vascular reconstruction. The goal is that these may one day be used to help patients who do not have other options for vascular reconstruction.
