Fig. 6From: Comparison of the ability of exosomes and ectosomes derived from adipose-derived stromal cells to promote cartilage regeneration in a rat osteochondral defect modelEffects of ASC-Ectos and ASC-Exos on apoptosis at 8 weeks of cartilage regeneration. (a) TUNEL staining of apoptotic cells in the repaired cartilage. (b) TUNEL staining of apoptotic cells in the adjacent cartilage. (c) Quantitative analysis of the cell apoptosis in the repaired cartilage. (d) Quantitative analysis of the cell apoptosis in the adjacent cartilage. Scale bar: 200 μm. *p < 0.05.
