Migration of M0, M1 and M2 macrophages in a TAXIScan. Representative pictures of a migration experiment in the TAXIScan. (A-C) Pictures at time (t) point zero (the cells that crossed the line have not migrated (*)), with all the cells lined up for migration. The cells tracked with ImageJ are visualized with dots. (D-F) Pictures taken after 1 h: lines represent the migration paths of the macrophages; F clearly shows that the M2 macrophages migrated further as indicated by the lines compared to M0 and M1.
