Chemotaxis versus chemokinesis of Cb2-expressing cells in response to 2-AG or SDF-1 using a transwell assay.
Cb2-transfected 32D/G-CSF-R cells, which naturally express CXCR4, were placed in the upper well with or without 2-AG or SDF-1α. Migration medium with or without ligand was placed in the lower well. Y-axis shows percentage of migration from an input of 1 × 105 cells.
