Effect of IL-3 on expression of chemokine receptors and integrins involved in migration of MSCs. BM-MSCs, AT-MSCs and GT-MSCs were treated with IL-3 (100 ng/ml) for 24 hours and surface expression of different chemokine receptors and integrins was analyzed by flow cytometry. a–c Fold change as percentage of cells expressing chemokine receptors and integrins. d Fold change in percentage of cells expressing intracellular CXCR4 analyzed after IL-3 treatment in permeabilized MSCs. Data shown as mean ± SEM of three independent experiments. *p ≤ 0.05 and **p ≤ 0.01 vs control groups.
