The purpose of these studies was an establishment of human auricular chondrocyte cell line using retrovirus mediated v-myc transfer, characterizing the human auricular chondrocyte cell line by type 11 collagen mRNA expression and transplantation of human auricular cell line into immunological incompetent nude mice to establish neocartilage formation. Also, I evaluated the growth rate of chondrocyte cell line to measure the cellular proliferative potency. I have established the human auricular chondrocyte cell line integrated v-myc and confirmed by v-myc transduced Myc protein expression by immunohistochemistry and immunoblotting study. And, growth rate of established human auricular chondrocyte cell line increased 4 folds times faster than primarily cultured human auricular chondrocyte. The established human auricular chondrocyte had type II collagen mRNA up to 8 months in monolayer culture. And we observed formation of neocartilage on the back of nude mice using chondrocyte cell linelfibrin glue polymer at 12 weeks transplantation.
