Accelerating protein release from microparticles for regenerative medicine applications

► A new delivery system providing controlled release kinetics has been developed. ► Inclusion of hydrophilic PLGA-PEG-PLGA decoupled release kinetics from degradation. ► Using 10% triblock copolymer produced quasi zero order release over four weeks. ► Mixing microparticle formulations provided another route for controlling release. ► This system provides customisable, localised and controlled delivery of growth factors.
