Immunohistochemical staining images revealing the presence of collagen type II (COL2A1) and type I (COL1A1). Chondrocytes were cultured in vitro with 0 (Control), 1.5 (T1), 3 (T2), and 6 μM (T3) ANDRO for 2, 4, and 6 days. Cell seeding density: 2 × 104/mL (original magnification × 100). Scale bar = 200 μm.
