Research Interest

Methods by which to decrease bone marrow stromal cell migration into the lungs have included demonstration that the SMAD3-/- bone marrow chimeric mice show decreased fibroblast migration in the lungs, due to their inability to respond to TGFβ, the cytotoxic cytokine and fibrosis inducing cytokines produced by irradiated lung. We have also demonstrated the bone marrow origin of fibroblast progenitor cells for the fibrotic lesions in pulmonary fibrosis. Research is currently underway to determine the initial molecular events in irradiated lung which lead to TGFβ production and initiation of migration of bone marrow cells forming fibrosis.
