- Abstract: 【Objective】 To investigate the effect and mechanism of musk-containing serum on the migration of bone marrow mesenchymal stem cells (BMSCs). 【Methods】 Sixty SD rats were randomly divided into four groups: musk-high-, medium- and low-dose groups and blank control group; medicated serum was prepared. Fifteen SD rats were isolated and cultured with BMSCs, and the third generation of BMSCs were identified by morphology, phenotype, osteogenic and adipogenic induction. BMSCs received medicinal healing intervention with high-, medium- and low- (16.8, 8.4, and 4.2 μL/100 g) musk, and the cell proliferation rate was detected by MTT assay. Under the intervention of the protein kinase C (PKC) signaling pathway (GF109203X), the effect of musk with pharmacition on the migration of BMSCSs was detected with the Transwell test. 【Results】 The rat BMSCs were attached to the wall, with orderly arrangement and good cell viability. Phenotypic identification revealed that the expressions of CD44 and CD90 were positive, while the expressions of CD45 and CD34 were negative, and the cells could differentiate into osteoblasts and adipocytes. The proliferation rates of BMSCSs with different concentrations at different time periods were higher than those in the blank control group (P<0.05). The number of BMSCs in the low-concentration musk group (4.2 μL/100 g) was significantly increased at 24 h, 48 h and 72 h after the addition of the blocking agent GF109203X (P<0.05). The migration quantity of the low-concentration musk group + blocker group (GF109203X) significantly decreased at different time periods, and there was no significant difference between different time groups (P>0.05). 【Conclusion】 The mechanism of musk-containing serum in promoting BMSCs migration may be related to the activation of PKC signaling pathway.
