| Abstract | Objective Our study focused on the effects and molecular mechanisms of kaempferol, a major active component of Eucommia ulmoides Oliver (EUO), on the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). Methods Target molecules for EUO, osteoarthritis, and osteogenic differentiation were identified through network pharmacology analysis. BMSCs were isolated and treated with various concentrations of kaempferol. Optimal concentration was determined through MTT assays. Osteogenic differentiation was assessed using alkaline phosphatase (ALP) and Alizarin Red S staining, while osteogenic markers (Collagen I, RUNX2, and OPN) and CAV-1 expression were analyzed using RT-qPCR and Western blot. The effects of combined treatment with kaempferol and an overexpression vector for CAV-1 (oe-CAV-1) on osteogenic differentiation were also observed. Results Network pharmacology analysis identified kaempferol as the primary active component influencing CAV-1 targeted in subsequent experiments. It was found that 10 µM kaempferol was optimal for treating BMSCs. Post-treatment, significant increases in ALP activity and calcium deposition were observed, along with elevated expression of osteogenic markers, and decreased CAV-1. Overexpression of CAV-1 significantly reversed the promotive effects of kaempferol on BMSC osteogenic differentiation, effectively inhibiting the process. Conclusion Collectively, kaempferol promotes osteogenic differentiation in BMSCs by inhibiting CAV-1 expression. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
