Fig. 11From: Umbilical cord mesenchymal stem cells derived extracellular vesicles can safely ameliorate the progression of chronic kidney diseasesKidney biopsy of a patient of the treatment group (HTN nephrosclerosis) x 630: Panel (a) showing the expression of CD133 in the renal tubular epithelial cells indicating active recovery of renal tubular cells. Panel (b) showing the expression of Ki67 mRNA abs indicating active proliferation of tubular epithelial cells. Both markers had not been shown in a similarly stained kidney biopsy of the control group. This represents strong evidence that these changes are related to the MSC-EVsBack to article page
