Fig. 2. Prevascularized TEBGs promoted repair of bone defects.
a After surgery, all rats were exposed to X-ray to affirm the model was successful. The images were collected at 1, 4 and 8 weeks after implantation. b, d Micro-CT 3D reconstruction images of the new bone formation and β-TCP matrix at 1, 4 and 8 weeks after surgery. c BV/TV was used to evaluate new bone formation. e RSV/SV was used to evaluate scaffold degradation. n = 10 samples per group. Data are represented as the mean ± s.e.m. *P < 0.05, **P < 0.01 as determined by Student’s t-tests. f H&E staining of rat femur sections at 4 and 8 weeks after the surgery
