Collagen hydrolysis efficiency as per hydrolyzing agent: (a) morphological observation, (b) total protein and hydroxyproline concentration, (c) cell proliferation comparison with MTT assay, and (d) cell morphological comparison. Data are presented as the values. The values with different superscript letters in a column are significantly different (). Scale bars, 50 μm. Ctrl, uncoated; 0.5 M acetic acid; coated with collagen hydrated with 0.5 M acetic acid; 0.5 M lactic acid, coated with collagen hydrated with 0.5 M lactic acid; 0.5 M NaOH, coated with collagen hydrated with 0.5 M NaOH; 1.0 N HCl, coated with collagen hydrated with 1.0 N HCl.
