Histological examination and protein evaluation of engineered cartilage after in vivo implantation. (A-O). Representative images of immunostaining for collagen type II (COL 2), elastin (ELN) and collagen type I (COL 1) in engineered cartilage, native ear cartilage and silk fibroin scaffold; (P-Y). picrosirius red staining examination under a polarized microscope; (Z). Quantification of glycosaminoglycan (GAG), total hydroxyproline (HYP), COL2, COL 1 and elastin (ELN), content of EC and AC constructs overtime. Scale bar = 100 μm. Data is expressed as the mean ± SD (n ≥ 3). * P < 0.05; ** P < 0.01. Abbreviations: AC: autologous auricular cartilage grafted in the subcutaneous layer. EC: engineered cartilage
