a Experimental images show that Molm13 cells migrate on the M210B4 cell leading edge toward the stromal cell nucleus. b Distance of Molm13 cells with respect to the nucleus center of M210B4 cells under tight adhesion. c Experimental images show the retrograde flow of M210B4 cells. d Velocities of retrograde flow of M210B4 cells and migration velocity of Molm13 cells on M210B4 with or without AMD3100 treatment
