In vivo Evaluation of a Novel Chitosan/HAp Composite Biomaterial as a Carrier of rhBMP-2

Autor: Toshiyuki Akazawa, Masaru Murata, Tadashi Iizuka, Haruhiko Kashiwazaki, Keisuke Yamaguchi, Naoki Harada, Nobuo Inoue, Junzo Tanaka, Toshiyuki Ikoma

Publikováno v: Journal of Hard Tissue Biology. 19(3):181-186

We developed a porous chitosan/ hydroxyapatite (HAp) composite, in which the HAp nanocrystals align along the chitosan molecules, and examined the biocompatibility, osteoinductive activity, and the ability to act as a carrier of recombinant human bon
