Our lab studies the role of bone marrow-derived cells in angiogenesis and skeletal muscle regeneration and how aging affects these phenomena. Macrophage polarization states exhibit different functions in muscle regeneration. MicroRNAs (miRNAs) are small, noncoding RNAs that inhibit gene expression, thereby regulating many processes, including immune cell differentiation. However, the regulating effect of miRNAs on macrophage polarization, and the subsequent effect on muscle regeneration, has not been elucidated. As a clinically active vascular surgeon, my long term goal is to develop therapies to enhance muscle regeneration and tissue engineering, thereby reducing limb amputations. Modulating macrophage polarization could become a therapeutic intervention in muscle regeneration and disease states associated with acute and chronic inflammation.
