1.   But if tumour cells spread, a process called metastasis, they can form tumours in vital organs such as the lungs.

2.   Systemic treatment of cancer is bedevilled by the similarity of tumour cells to normal cells, at least under most physiological conditions.

3.   The search for anti-cancer drugs, for example, usually involves trials of chemical compounds on human tumour cells.

4.   The tumour cells grown from nude mice were also found to have HPV DNA sequences.

5.   This results, however, most probably reflects local response to treatment with the eradication of aneuploid tumour cells in a proportion of carcinomas.

6.   The integrin mediated interactions between tumour cells and the surrounding extracellular matrix are thought to play crucial parts in the complex process of invasion and metastasis.

7.   These results indicated that v containing integrins are essential for adhesion of these tumour cells to fibronectin.

8.   Recent studies have shown that inhibitors of the N-glycan processing reduce metastatic growth of tumour cells of different histological types and origins.

9.   All xenografts were mainly of tumour cells and very little tumour stroma.
