Fig. 3From: Prevascularization promotes endogenous cell-mediated angiogenesis by upregulating the expression of fibrinogen and connective tissue growth factor in tissue-engineered bone graftsPrevascularization increased expression of CTGF. (A) At 1 week post operation, immunofluorescence images of CTGF (red) and Hoechst 33342 (blue) from TEBG sections and prevascularized TEBG sections: far from blood vessel (a), center (b), and close to blood vessel (c); scale bars = 100 μm. (B) Relative fluorescence integrated optical density (IOD) of CTGF, n = 5. Data presented as mean ± s.e.m. **P < 0.01, *** P < 0.001 determined by Student t test.
