Research Abstract |
To promote clinical application of cartilage tissue engineering, we should establish a serum-free chondrocyte growth medium. We examined the combinations of growth factors and the methods to enhance their effects by making use of the interaction with biomaterials. From various growth factors that are contained within the serum, we made the cocktail of FGF-2 , insulin, EGF, PDGF and TGF-b, Moreover, we used the biomaterials including albumin and hyaluronan as the carrier of those factors. By direct mixing of those factors with biomaterials before the administration to the medium, the medium containing those mixture showed the chondrocyte growth of approximately a 25-fold increase by day 10. Due to the optimal usage of biomaterials, this serum-free medium will realize a constant harvest of chondrocytes and could contribute to the safety and quality in regenerative medicine.
