Tumour growth involves anomalies in cell cycle genes and emergent phenotypes, but the tumour proliferation rate (or mitotic index) is defined by just one marker, Ki-67. A study now integrates expression patterns of several markers to generate spatio-temporal maps of cell proliferation in cancer tissues.
