제목 PLGA Scaffold as Novel Drug Carriers for Protein
초록 Recently, the study of special protein release has attracted much attention for example, sustained release of active growth factors (such as EGF, NGF and BDNF etc.) are required in order to achieve desirable therapy for tissue engineering research due to the shortness of in vivo half-lives of the proteins. In this study, we reported the preparation and characterization of a novel biodegradable protein delivery device based on the PLGA scaffold. PLGA scaffold as a protein carrier prepared by a novel ice particle leaching method. Bovine serum albumin (BSA) is used as a model protein to examine the release behavior of prepared PLGA scaffold. BSA-loaded PLGA scaffolds were characterized by scanning electron microscopy (SEM) and mercury porosimetry, and the BSA release pattern was analyzed by fluorescent spectrometer. BSA-loaded PLGA scaffolds exhibited porosity above 90% medium pore size ranging from 180 to 250 ㎛. The feasibility of using the PLGA for the incorporation of BSA in a controlled-release implant form is investigated for the improvement of BSA release capability.
