Zusammenfassung: | To explore self-made graphene/β Graphene (G)/β- tricalcium phosphate, G/β- The effect of TCP composite scaffold material on osteogenic differentiation of BMSC. Preparation of G/β- TCP composite material was used to investigate the effect of composite material on bone marrow mesenchymal stem cell ossification/β- TCP material was used to treat primary BMSCs of rats. Cell morphology changes were observed under scanning electron microscopy, cell cycle and proliferation were detected by flow cytometry, and gene expression of chondrogenic genes Fibronectin, collagen I, collagen II, ICAM, and VCAM was detected by q-PCR. In addition, using osteogenic induction medium and G/β- TCP composite materials were co treated with BMSCs, and ALP and alizarin red staining were used to observe the effect of the materials on osteogenic differentiation. q-PCR was used to detect the gene expression of osteogenic related genes Runx2, OCN, and OPN. G/ β- After the TCP composite was co cultured with BMSC, the proportion of G0/G1 phase of BMSC cells was significantly increased, the cell proliferation ability was enhanced, and the gene expression of fibronectin, collagen I, collagen II, ICAM, and VCAM were significantly increased. The ALP staining results indicate that BMSC in G/β- After treatment with TCP composite material, significant enhancement of osteogenic ability was observed at 7,14 and 21 days. In addition, BMSC in G/β- A significant increase in calcium deposition was observed at 7,14 and 21 days after treatment with TCP composite materials. The effect of different time points on the expression of osteogenic related genes varies. At 7 and 14 days, the expression of RUNX2 was significantly reduced compared to the control, but significantly increased at 21 days; OCN significantly increased on the 21st day; OPN significantly increased at 14 days. G/β- TCP materials significantly promote the osteogenic differentiation of BMSCs. |
