Fabrication and controlled release of poly(DL-lactic-co-glycolic acid) (PLGA) microspheres. (A) Light microscopy of PLGA microspheres encapsulating transforming growth factor β-3 (TGFβ3). (B) Scanning electron microscopy (SEM) showing smooth spherical surface of PLGA microspheres with average diameter of 102 ± 45 μm. (C) SEM of the cross-section of a PLGA microsphere illustrating the crystal-like structure of encapsulated molecules. (D) Cumulative release profile of TGFβ3 from PLGA microspheres.
