In control 5/6 NE rats that had mild hematuria, <10% of the tubules expressed vimentin (mesenchymal marker), whereas in 5/6 NE rats that were treated with warfarin and had moderate chronic hematuria, over 30% of the tubules expressed vimentin in tubular epithelial cells (Figures 5B,C). This evidence concerns the gene VIM and Hematuria.
