RT-qPCR analysis of the COL1A1, COL2A1, and ACAN expression levels in the construct with the cell density gradient and the construct with the homogeneous cell distribution in Groups A, B, and C after 3 weeks of in vitro culture. COL1A1: collagen type I; COL2A1: collagen type II; ACAN: aggrecan. The * indicates significance (p < 0.05). The error bars show the SD (n = 3)
