Fig. 2From: Insulin-like growth factor-1 in articular cartilage repair for osteoarthritis treatmentTissue engineering-based IGF-1 delivery. MSCs, such as ADSCs, SF-MSCs, and BM-MSCs, are seeded on scaffolds. The addition of IGF-1 can induce chondrogenic differentiation of MSCs and promote cartilage tissue formation, cartilage matrix GAG accumulation, and type II collagen production, thus promoting cartilage regeneration and cartilage defect repairBack to article page
