title: Motility of leukemic cells in collagen gel related to immunological phenotype in childhood acute lymphoblastic leukemia.
abstract: Motility of leukemic cells was measured in a three-dimensional collagen matrix assay. Leukemic cells from 16 children with acute lymphoblastic leukemia (ALL) and normal peripheral blood lymphocytes (NPBL) from 6 healthy volunteers, were allowed to migrate into this collagen matrix for 48 h at 37 degrees C. NPBL migrated much further (300-600 micron) than leukemic cells (0-200 micron). Among the leukemic cases, only common ALL and one case of null ALL showed some migration (0-200 micron). T-All cells did not migrate at all under the circumstances of this experiment.
