ABSTRACT
Autologous chondrocyte (CH) transplantation is a novel strategy to treat post-traumatic osteoarthritis (PTOA). In this study, an in vitro coculture model was used to explore the effects of interleukin (IL)-10 overexpressed CHs on degenerated CHs. The original CHs were isolated from the patients' knee joint cartilage and pretreated with IL-1ß to get degenerated CHs. Moreoer, CHs were transfected with a lentivirus vector to overexpress IL-10. After coculture with the degenerated CHs, the apoptosis, collagen X, IL-6, and TNF-α of original CHs were increased, and the collagen II and IL-10 were decreased compared to the separated culture condition. Coculture with original CHs did not alleviate the degeneration of the IL-1ß-pretreated CHs. However, coculture with the IL-10-overexpressed CHs rescued the proliferation, collagen II, aggrecan, SOX9, and IL-10 expression, and suppressed the apoptosis, collagen X, RUnx2, IL-6, and TNF-α levels in the IL-1ß pretreated CHs. Additionally, the IL-10-overexpressed CHs also maintained a healthy state when cocultured with the degenerated CHs. Therefore, transplanting the IL-10-overexpressed CHs in the treatment of PTOA would obtain a more durable and visible effect in alleviating the CH degeneration.
