Collagen plays a crucial role in cancer development and migration. However, the impact of changes in the collagen molecular structure on its interaction with cancer cells remains unclear. In this study, natural bovine tendon collagen was heat-treated to obtain collagen samples with different triple helix dissociation degrees. Three methods, including cell adhesion assay, fluorescence labeling assay, and cancer cell capture assay, were employed to compare the binding efficiency of collagen samples to both breast cancer cells (MCF-7) and human um...
