Abstract: Here, we present a photodegradable microparticle system that can be employed to entrap and deliver bioactive proteins to cells during culture. By using a photosensitive delivery system, experimenters can achieve a wide variety of spatiotemporally regulated release profiles with a single microparticle formulation, thereby enabling one to probe many questions as to how protein presentation can be manipulated to regulate cell function. Photodegradable microparticles were synthesized via inverse suspension polymerization with a mean diameter of 22 ?m, and degradation was demonstrated upon exposure to several irradiation conditions. The protein-loaded depots were incorporated into cell cultures and release of bioactive protein was quantified during the photodegradation process. This phototriggered release allowed for the delivery of TGF-?1 to stimulate PE25 cells and for the delivery of fluorescently labeled Annexin V to assay apoptotic 3T3 fibroblasts during culture.
