Abstract

The potential relevance for improving bone formation in and around tissue-engineered constructs. The objectives of this study were to investigate erosion and release of biologically active protein from CAP/PF-127 blends in an environment more representative of local growth factor delivery into a low clearance site. Within this study, effects of polymer blend ratio, sampling interval, and multilayering were examined with the ultimate goal of obtaining multiphasic release profiles over a period of several days.
