(A,B) Biomaterial degradation of scaffolds with culture. (A) Histology and (B) ratio (Wb/Wp) of 3D-printed scaffolds at day 1, 3, 5, 7, and 14 of culture (scale bar: 50 μm for day 3; 200 μm for day 5, 7 and 14, respectively; arrow: embedded cell). (C) BMP-4 release from 3D-printed scaffolds over time. Data are mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001.
