Colorectal cancer cells growing in a lab. Colours have been added by the researchers to label different proteins inside the cells. The colourful cells have unusual properties and can potentially be used to study the effectiveness of new anti-cancer drugs.

Visualised using confocal microscopy by Dr Kristina Jahn, University of Sydney.

Size: the cell island is about 400 micrometres across.
