A Sox9 expression of MSCs seeded in scaffold of collagen/chondroitin sulfate (CCS) with different compressive modulus (stiffness). B Amount of CS (chondroitin sulfate) in two different type of collagen scaffolds at initial time and after 3 days of incubation in cell culture media. 2af-CS and 2rf CS indicate afibrillar type II collagen-CS and fibrillar type II collagen-CS scaffolds, respectively.
