Organ-chip models of tumour growth and cancer cell proliferation. (A) Proliferation of cancer cells over 5 days in a chip model of human colon carcinoma (red = dead cells; green = live cells; scale bar = 400 µm) [31]; (B) A chip co-culture used to investigate the growth of (1) lung tumours and (2) skin microtissues over 5 days (scale bar = 500 µm) [32]; (C) A chip model exploring the proliferation of cervical cancer cells over 5 days, with staining delivered via tumour targetting nanoparticles [33].
