Migration, proliferation, and elasticity of bladder cancer cells on lectin-coated surfaces

Abstract

The alterations in migration, proliferation, and mechanics of cells observed during cancer progression can potentially be linked to enhanced tumor invasiveness. These properties are frequently attributed to the ability to form distant metastasis; however, the direct mutual connection between these properties is not always proven. Here, we studied the migratory, proliferative, and mechanical phenotype of three bladder cancer cells originating from various stages of cancer progression, i.e., non-malignant cell cancer of ureter (HCV29 cells), bladder carcinoma (HT1376 cells) and transitional bladder carcinoma (T24 cells). The results were linked with the organization of actin filaments because of their major role in cell migration. The results classified cells into non-malignant, non-invasive, and invasive, revealing the significant impact of actin filaments in bladder cancer invasion. Based on the reported changes in cancer cell glycosylation, the potential applicability of the observed cancer-related changes to identify invasive cells was demonstrated for the lectin-coated surfaces, which is the potential surface modification for biosensors.
