Fig. 3. (a) Gelation time of control HP-T/HP-A (CTRL), CNTs and CNTs/BMP-2 scaffolds. (b) Gelation characteristics of CTRL and CNTs as determined by in situ rheometry at 37 °C. Occurrence of a gel point as crossover between G′ and G′′. G′, solid symbols; G′′, open symbols. Concentration of BMP-2 was 50 ng mL−1 of gel scaffolds. Values reported are an average n = 5, ±standard deviation.
