摘要
The research focusing on injectable material for tissue engineering has encouraged the investigation of gel formation derived from succinylated poly(Pro-Hyp-Gly) and chitosan. This paper describes a preliminary study on gelation of both materials to obtain a new material for cartilage repair. Poly(Pro-Hyp-Gly) shows a collagen-like triple helical structure as a major component of extracellular matrix of cartilage. Furthermore, the cationic nature of chitosan is similar in chemical structure with various glycosaminoglicans in cartilage. Through polyion complex interaction between carboxy group of succinylated poly(Pro-Hyp-Gly) and amino group of chitosan, viscous solution containing gel particles was obtained.
