Observation and protein expression of BMSCs expressing eGFP.

<p>A: Expression of eGFP was observed in BMSCs. Selection using DMEM/F-12 culture medium containing 0.5 μg/ml puromycin yielded transduced cells with constant, stable, and bright green fluorescence after 3 weeks. B: SDF-1 and MCP-1 of BMSCs expressing eGFP by ELISA.SDF-1 and MCP-1 protein expression of BMSCs expressing eGFP in ex vivo cultures at days 3, 7, and 14. The quantity of SDF-1 and MCP-1 gradually increased with time. *<i>p</i> < 0.05, <i>n</i> = 4.
