- Paper Abstract
- The regulation of stem cell directional differentiation is a core research topic in regenerative medicine, and modulating the fate of stem cells is a promising strategy for precise intervention through the utilization of naturally small molecule compounds. The present study aimed to explore the potential pro-osteogenic differentiation effect of galangin, a flavonoid derived from Alpinia officinarum, on human amniotic mesenchymal stem cells (hAMSCs) and the underlying molecular mechanism. The results showed that galangin had no cytotoxicity towards hAMSCs when the concentration was less than 50 μM. Treatment with 10 μM galangin significantly increased alkaline phosphatase (ALP) secretion and calcium deposition in hAMSCs. Meanwhile, galangin upregulated the mRNA and protein expression of early osteoblast-specific markers, namely ALP, RUNX2, and OSX, and late osteoblast-specific markers, CoL1α1, OPN, and OCN, in hAMSCs. Furthermore, signaling pathway screening studies showed that galangin enhanced the phosphorylation of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3). In addition, molecular docking results suggest there is a promising interaction between galangin and JAK2. Finally, treatment with the JAK2 specific inhibitor AG490 effectively reversed the induction of osteogenic differentiation, upregulation of osteoblast-specific marker expression, and activation of JAK2/STAT3 signaling induced by galangin. These results show that galangin induces the osteogenic differentiation of hAMSCs through the JAK2/STAT3 signaling pathway and could serve as a promising small molecular osteoinducer for application to hAMSCs in regenerative medicine.
