Figure 4. Cellular contributors to myofibroblast recruitment and subsequent tubulointerstitial fibrosis in DKD.
The myofibroblasts responsible for the matrix deposition that leads to tubulointerstitial fibrosis in DKD are derived from a variety of sources, with transformation of local resident fibroblasts, mesenchymal stem cells and bone marrow derived fibrocytes and the induction of endothelial to mesenchymal and tubuloepithelial to mesenchymal transitions the main contributors.239
