ABSTRACT

BACKGROUND:

It is an urgent problem to effectively make bone marrow mesenchymal stem cells exert proper effects under hypoxic preconditioning.

OBJECTIVE:

To investigate the effects of diazoxide, a Mito-KATPchannel activator, on the proliferation and apoptosis of mouse BMSCs in hypoxic environment.

METHODS:

Mouse BMSCs were divided into four groups blank control group, 0.16, 0.8, 4 μmol/L diazoxide groups. Cells intervened by diazoxide were cultured in a 10% O2incubator. MTT assay was performed to detect cell proliferation at 1, 2, 4, 6, 8 days after intervention, and Hoechst 33258 staining was performed to observe cell apoptosis at 14 days after intervention. RESULTS AND

CONCLUSION:

High homogeneity and purity but low proliferation of BMSCs was found. There was no significant difference in the activity of BMSCs among 0.16, 0.8, 4 μmol/L diazoxide groups (P > 0.05). In the blank control group, concentrated nuclei were dark blue in color and aggregated, and several round apoptotic bodies were found. In the diazoxide groups, apoptotic bodies were occasionally found, and no significant difference was found among different diazoxide groups. These findings indicate that a certain concentration of diazoxide can reduce cell apoptosis but has no effects on the proliferation of mouse BMSCs under hypoxic environment (10% O2).
