Skin Cancer cells work together to spread further and faster, according to a new study published in Cell Reports. The discovery could lead to new drugs to tackle melanoma, the most deadly form of skin cancer.
Cancer Research UK scientists at The University of Manchester found that some melanoma cells are particularly fast growing, but not very good at invading the surrounding tissue, while other melanoma cells are the opposite – highly invasive but slow-growing.
In a tumour, the faster growing cells ’piggy-back’ along with the more invasive cells, so together they can be more effective in establishing a new tumour once they have reached different parts of the body.
The scientists conducted the research using see-through zebra fish so that they could see how the cancer cells moved and expanded from the original tumour.
Dr Claudia Wellbrock, study author and Cancer Research UK scientist at The University of Manchester and a member of the 91直播 Cancer Research Centre, said: “We used to think that cancer cells spread by first specialising in invading other parts of the body and then change in order to grow rapidly. But this research shows that melanoma can spread by ‘co-operative invasion’.
“Different types of cancer cells with different strengths and weaknesses are both present in the tumour at the same time and can work together to spread faster and more efficiently. This has profound implications for how we find cures for this terrible disease.”
Melanoma is the most dangerous form of skin cancer with around 13,300 people diagnosed in the UK each year. Worryingly, the incidence rates of malignant melanoma have increased more than fivefold since the mid 1970s.
Professor Richard Marais, director of the Cancer Research UK 91直播 Institute, said: “Malignant melanoma is the most deadly form of skin cancer precisely because it spreads quickly and aggressively. This kind of research is vital for establishing how this horrible disease spreads around the body and how we might be able to stop it.
“As well as finding more effective treatments for advanced melanoma, we also need to stress the importance of early diagnosis, detecting tumours before they have a chance to spread.”

91直播 Cancer Research Centre –
The 91直播 Cancer Research Centre (MCRC) is a partnership founded by The University of Manchester, including the Paterson Institute for Cancer Research, The Christie NHS Foundation Trust and Cancer Research UK. The MCRC brings together the expertise, ambition and resources of its partner organisations in the fields of cancer treatment and clinical research and provides outstanding facilities where researchers and clinicians can work closely together. The aim of the MCRC is to improve understanding of how cancer develops, in order to translate basic and clinical research into new diagnostic tests and treatments that benefit cancer patients.
The University of Manchester
The University of Manchester, a member of the prestigious Russell Group of British universities, is the largest and most popular university in the UK. It has 20 academic schools and hundreds of specialist research groups undertaking pioneering multi-disciplinary teaching and research of worldwide significance. According to the results of the 2008 Research Assessment Exercise, The University of Manchester is one of the country’s major research institutions, rated third in the UK in terms of ‘research power’, and has had no fewer than 25 Nobel laureates either work or study there. The University had an annual income of £807 million in 2011/12.
