Two-dimensional trajectory plots of M0, M1 and M2 for CCL2, CXCL12 and C1q. Representative figures of the directed cell migration in the TAXIScan; the upper panel shows migration tracks of M0, M1 and M2. The centre of mass is depicted with a red triangle, M2 and M0 migrate comparable towards CCL2. The middle panel shows migration of M0, M1 and M2 towards CXCL12; M2 migrates over larger distances than M0 and M2. C1q is the most powerful attractant for M2 macrophages, as represented in the lower panel. CCL, Chemokine C-C motif ligand; CXCL, Chemokine C-X-C motif ligand.
