From: Mesenchymal stem cell treatment for chronic renal failure
Stenotic-kidney microvascular loss and fibrosis decreased in animals treated with mesenchymal stem cells. Top: representative microcomputed tomography three-dimensional images of kidney segments, showing improved microvascular architecture in pigs with atherosclerotic renal artery stenosis (ARAS) treated with percutaneous transluminal renal angioplasty (PTRA) and an adjunct intrarenal infusion of adipose tissue-derived mesenchymal stem cells (MSC) 4 weeks earlier. Bottom: representative renal trichrome staining (×40, blue) showing decreased fibrosis in ARAS + PTRA + MSC pigs.
