Cancer Cells Leaving Tracks

Micrograph of a region of zebrafish skin where a track of cancer cells has disrupted the epithelium much like a mole burrowing beneath a lawn of grass. Cancer-related inflammation impacts significantly on cancer development and progression. New research has observed in zebrafish, for the first time, that inflammatory cells use weak spots or micro-perforations in the extracellular matrix barrier layer to access skin cancer cells.
