Based on the multistep model of cell migration chemokine receptor engagement (step 2 2) triggers conversion of rolling interactions (step 1 1) into firm adhesion (step 3 3) yielding transendothelial migration. osteotropism visualized by intravital microscopy. Here we performed studies to define the molecular effectors of this process. We observed that engagement of hMSC HCELL… Continue reading Based on the multistep model of cell migration chemokine receptor engagement
