Phenotypic characterization of transmigrated antileukemia T-cell lines. Data represent both input (upper section) and migrated cell populations after the 6-hour chemotaxis assay through HUVEC endothelial cell layer (middle section) or the BMEC endothelial cell layer (lower section). The results are from a single patient and are representative of 3 different patients. Open areas represent fluorescence distribution of the molecules indicated and solid areas represent that of isotype-matched control antibodies. The cell number is shown on the y-axis.
