Kartogenin is a potent inducer that promoting the differentiation of multipotent mesenchymal stem cells (MSCs) into chondrocytes with EC50 value of 100 nM [1].

MSCs are a kind of stem cell that can differentiate into different cell types including chondrocytes, osteoblasts, adipocytes and myocytes.

Kartogenin (KGN) potently induced the differentiation of hMSCs into chondrocytes in a dose-dependent way [1]. In preskeletal mesenchymal cells from mice, KGN stimulated the formations of cartilage nodule and synovial joint, boosted digit cartilaginous anlaga elongation and stimulated interdigit invagination, tendon maturation and interzone compaction. KGN increased the expression of TGFβ1, which stimulated cartilage nodule formation. Also, KGN increased the phosphorylation of Smads that mediated BMP and TGFβ signaling [2].

In the acute surgical model and the chronic joint injury model, kartogenin showed chondroprotective effects. Kartogenin disrupted the interaction of filamin A and the transcription factor core-binding factor β subunit (CBFβ) and regulated the CBFβ-RUNX1 transcriptional, which then induced chondrogenesis [1]. In the dermis of BALB/C mice, KGN induced synthesis of type-I collagen and activated Smad4/smad5 signaling pathway of the TGF-β [3].
