Fig. 2From: A model for the dissemination of circulating tumour cell clusters involving platelet recruitment and a plastic switch between cooperative and individual behavioursThe effect of TGF-β1 on the migration of H2122 SS cells. The number of H2122 SS cells that migrated through a Transwell insert after 24 h (a) and 48 h (b) post-seeding. Pictures are sample fields of view showing cells (purple dots) that have migrated through the pores (empty circles) and adhered to the underside of the insert (cells were stained with 0.2% crystal violet).
