Subsequently, to investigate EGCG’s effects on chondrocytes under osteoarthritis (OA)-mimicking conditions, cells were stimulated with IL-1β (10 ng/mL) for 24 h to establish the disease model group (Model), followed by treatment with 10 μg/mL EGCG for an additional 24 h (EGCG group). Here, IL1B is linked to osteoarthritis.
