Characterization of carriers: morphology, particle size distribution and hTGF-β1 release profiles for PLGA-MCs. SEM image (a) and particle size distribution (b) of PLGA carriers obtained after SEE process; size distribution data are expressed as volume percentage. hTGF-β1 release profiles expressed as percentage of total load and monitored at 37 °C and 100 rpm by ELISA-based assay; n = 3 (c); hTGF-β1 amount (ng/mL/day) released within each 3D-scaffold loaded with 6.6 mg of carriers in dynamic condition (d).
