Auricular Cartilage Regeneration with Adipose-Derived Stem Cells in Rabbits
Expression of collagen type II, TGF-β1, and IGF-1. The relative expression of collagen type II (a) and TGF-β1 (b) were significantly higher in the ASC group than in the PBS group. However, there was no significant difference in the expression of IGF-1 between the ASC and PBS groups (c). Data are expressed as the mean ± SEM. and . ASCs, adipose-derived stem cells; PBS, phosphate-buffered saline.
