TSA, tubacin, and niltubacin do not modify the polarization of PBL induced by SDF-1. PBL were treated as indicated and then allowed to adhere to FN-coated coverslips for 15 min. Cells were then fixed and stained with an anti-ICAM-3 mAb followed by an FITC-labeled secondary antibody. Cell polarization was determined as stated in Materials and Methods. The arithmetic mean ± SD of three independent experiments is shown.
