a, Left and middle, schematic of Rheology experimental outline. Right, Quantification for the modulus of the regenerate (PBS, BMP2, BMP2 + sVEGFR1.) Graph shows mean + /- s.e.m. Ordinary one-way ANOVA test (p = <0.0001) with post-hoc analysis using Šídák method to compare between specific means. Exact P values to 2 significant figures. (n = 10 mice per group). b, From left-right, gross images of distal femur (scale bars 1 mm); respective pentachrome (scale bars 500μm); 3D Peak Force Error; 3D Deformation; Force Volume in 4 conditions (PBS, BMP2, BMP2 + sVEGFR1, Uninjured) (n = 4 per group). Scale bar 500μm. c, Force graphs for PBS, BMP2, BMP2 + sVEGFR1, and uninjured. (n = 4 per group).
