| Research Abstract |
We investigate the cartilage tissue engineering in vivo by using rat model. Mesenchymal stem cells, isolated from rat bone mallow, were cultured and differentiated to chondrocyte by the growth factor, TGF-β1. The differentiated cells were seeded into the collagen gel scaffold and 3-D cultured. It resulted in increased cartilaginous tissue in part. Additionally, due to develop the recipient bed for cartilage tissue engineering in vivo, we attempted to make granulation tissues in vivo by mimicking the chamber method. Subsequently grafted skin was well survived on this granulation tissue, and it seemed that this granulation tissue could be the recipient bed for cartilage tissue engineering in vivo.
