(From Bristol Evening Post)
BRISTOL scientists have discovered how cancer cells spread - by studying fish.
By capturing film of the cells in translucent zebrafish, the Bristol University researchers found that newly formed cancer cells can take over the immune system and cause the disease to spread.
The discovery could lead to potential new treatments being developed to eliminate early-stage cancer in humans.
The scientists from Biochemistry and Physiology & Pharmacology used different coloured fluorescent tags to label immune cells and tumour-forming cells in the fish and filmed them to track their behaviour and interactions.
