a Confocal images of VCAM-1 staining on M210B4 stromal cells. The scale bar is 20 µm. b Total adhesion percentage of Molm13 cells assembled at different positions of M210B4 cells. Two groups of Molm13 cells, namely, the normal group and group treated with 1 µM AMD3100 for 2 h before experiments. c Tight adhesion percentage of Molm13 cells assembled at different positions of M210B4 cells. Two groups of Molm13 cells, namely, the normal group and group treated with 1 µM AMD3100 for 2 h before experiments were studied.*P < 0.05. **P < 0.01
