(A) 4 h and 8 h MSC adhesion on 3D printed scaffolds with and without RGDS, (B) 48 h MSC growth on the 2D culture plates under varied LIPUS treatment conditions. Data are mean ± standard error of the mean, n = 9. *p < 0.05, **p < 0.01 when compared to corresponding scaffolds without RGDS in each group. $p < 0.05 when compared to all other scaffolds with RGDS. #p < 0.05 when compared to all other scaffolds without RGDS. &p < 0.05, @p < 0.01 when compared to all other groups with various LIPUS intensities.
