Quantification of cell proliferation by detection of DNA content and matrix production by glycosaminoglycan (GAG) analysis. (a) The proliferation of chondrocytes cultured in vitro with 0 (Control), 1.5 (T1), 3 (T2), and 6 μM (T3) ANDRO for 2, 4, and 6 days; (b) GAG (mg) normalized to DNA (mg). Data from 3 independent experiments were evaluated, and the mean ± SD is shown. , ∧ indicate ; , ∧∧ indicate ;, ∧∧∧ indicate .
