BMP-2 release profiles from PLGA and PLGA-MBG scaffolds with 20 μg BMP-2 adsorption. The amount of BMP-2 released from scaffolds was determined by ELISA.
Notes: P2, P4, or P8 represents the PLGA scaffold coated by MBG precursor solution for 2, 4, or 8 times, respectively. P0 represents the unmodified PLGA scaffold.
Abbreviations: BMP-2, bone morphogenetic protein-2; MBG, mesoporous bioactive glass; PLGA, poly(lactic-co-glycolic acid); ELISA, enzyme-linked immunosorbent assay.
