| Abstract: |
| This study was to initiate in vitro culture of shark cartilage cells. Fin and gill cartilage tissues digested by hyaluronidase(0.5%), Type II callagenase(0.2%) and trypsin(0.25%) were chosen for the initiation. Then the digested tissues and dissociated cells obtained were cultured in 20% newborn bovine serum(NBS) containing MEM medium. The results show that cultured cartilage cells began to migrate out of tissues 3 days after the culture initiated. And they became round or oval shape immediately after the migration, and some of them changed gradually into epithelioid shape later. It was found that the optimal pH value and temperature for cultured cartilage cells is 7.2, and 24℃, respectively. Under the optimal conditions, the culturing cartilage cells were in a good growing status, and they grow and proliferate rapidly. The effect of basic fibroblast growth factor(bFGF) on culturing cartilage cells was also investigated in this study, and no obvious growth and proliferation stimulating effect was observed. |
