Abstract Background Bone disease causes short-term or long-term physical pain and disability. It is necessary to explore new drug for bone-related disease. This study aimed to explore the role and mechanism of Salidroside in promoting osteogenic differentiation of adipose-derived stromal cells (ADSCs). Methods ADSCs were isolated and treated with different dose of Salidroside. Cell count kit-8 (CCK-8) assay was performed to assess the cell viability of ADSCs. Then, ALP and ARS staining were conducted to assess the early and late osteogenic capacity of ADSCs, respectively. Then, differentially expressed genes were obtained by R software. Then, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the differentially expressed genes were further analyzed. The expression of OCN, COL1A1, RUNX2, WNT3A, and β-catenin were measured by real-time PCR and Western blot analysis. Last, β-catenin was silenced by small interfering RNA. Results Salidroside significantly increased the ADSCs viability at a dose-response manner. Moreover, Salidroside enhanced osteogenic capacity of ADSCs, which are identified by enhanced ALP activity and calcium deposition. A total of 543 differentially expressed genes were identified between normal and Salidroside-treated ADSCs. Among these differentially expressed genes, 345 genes were upregulated and 198 genes were downregulated. Differentially expressed genes enriched in the Wnt/β-catenin signaling pathway. Western blot assay indicated that Salidroside enhanced the WNT3A and β-catenin expression. Silencing β-catenin partially reversed the promotion effects of Salidroside. PCR and Western blot results further confirmed these results. Conclusion Salidroside promoted osteogenic differentiation of ADSCs through Wnt/β-catenin signaling pathway.

Chondrogenic Phenotype

Abstract Articular cartilage is the connective tissue that lines the surfaces of diarthrodial joints in the human body. Because cartilage is avascular, aneural, and alymphatic, it has a limited capacity for repair. Techniques such as microfracture, transplantation of autologous cartilage, and allograft or xenograft transplantations have not proven fully effective in treating cartilage damage. Current therapy is focusing on cell-based treatments such as autologous chondrocyte transplantation [1,2]. However, this method faces several limitations, as the donor site can provide a limited number of cells and the harvesting procedure itself may cause significant local morbidity. The goal of this study was to examine the chondrogenic potential of an autologous source of undifferentiated stromal cells derived from subcutaneous fat. It has been shown that chondrocytes embedded in a three-dimensional matrix retain a differentiated phenotype and produce cartilage-associated proteins [3]. In addition, it has been shown that alginate or agarose can support the formation of an extracellular matrix over time [4,5]. The goal of this study was to examine the chondrogenic potential of adipose-derived stromal cells with the ultimate goal of developing a “tissue engineering” method to regenerate articular cartilage.
