Anti-CK MAb reduces the invasiveness of MCF-10A neoT cells. The degree of invasion of Matrigel by MCF-10A neoT cells is shown in the presence and absence of anti-CK MAb. It is presented as the percentage of invasion of MCF-10A neoT cells to the lower compartment of a Transwell chamber. Bars represent mean percentages of migrated cells ± s.d. P values < 0.001 are marked with **.
