Cartilage is a tissue that has a low potential for self-repair. One of the methods for improvement of regeneration and metabolism in cartilge, is to stimulate physical factors on chondrocytes as cartilage based cells. In this research, two physical factors, oxygen tension and pH, were changed to measure the cell viability of chondrocytes on Degrapol®, as a biodegradable polyurethane (DBS), and alginate scaffolds and cell viability onto these substrates are compared. The results showed that, physical factors like oxygen and pH could change cell viability. After 3 days cell culture for both types of scaffolds, the cell viability was higher with 5% O2 and pH=7.4 and it was not dependent on the type of scaffolds. Our results showed that cell viability on alginate beads is more than DBS scaffold for different conditions.
