Tumour blood vessels prevent the spread of cancer cells
A lack of the protein endoglin in the blood vessels of tumour-bearing mice enables the spread of daughter tumours, according to researchers at Karolinska Institutet and Lund University, Sweden, in a study published in the scientific periodical The Journal of Experimental Medicine. Given that the tumour vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to strengthen the blood vessels’ protective function.Studies of the process of metastasis (the spread of daughter tumours) have mainly focused on how the properties of
