Fig. 6From: Enhanced therapeutic effects of MSC-derived extracellular vesicles with an injectable collagen matrix for experimental acute kidney injury treatmentTreatment of Col-EVs accelerated renal recovery. a Serum creatinine and b BUN levels were measured at different time points after severe AKI (n = 5. *P < 0.05 vs. sham; #P < 0.05 vs. PBS). c Representative images of kidney sections stained with HE at day 3 after AKI. Scale bar, 50 μm. d Masson trichrome staining and α-SMA staining (e) were performed to describe collagen deposition 1 month after AKI. Scale bar, 50 μm and 100 μm, respectivelyBack to article page
