Research Abstract

To clarify the pathogenesis of renal fibrosis leading to chronic renal disease, functional properties of macrophages and myofibroblasts appearing in kidney injured tissues were investigated pathologically. It was found that heterogeneous macrophages appeared, and that then factors produced by macrophages could induce myofibroblasts. Inhibition of macrophage functions may improve renal fibrosis. Additionally, hepatic fibrosis and wound healing fibrosis were analyzed comparative-pathologically.
