Auricular Cartilage Regeneration with Adipose-Derived Stem Cells in Rabbits
Gross findings of auricular cartilage defect. (a) The defect of control group remained thin around the perforation. (b) In the ASC-treated ears, the defects were completely repaired by chondrocytes with smooth surface and similar color with the surrounding tissue. (c) The defect size was significantly smaller in the ASC group than in the PBS group. Data are expressed as the mean ± SEM. . ASCs, adipose-derived stem cells; PBS, phosphate-buffered saline.
