Abstract

Here, we report the behavior of three kinds of human cancer cell lines (Caco-2, MCF-7, HT-1080) on type I collagen substrates, which are in two-dimensional coated collagen or three-dimensional fibrils form. All tested cells on coated collagen adhered and proliferated. However, in the case of collagen fibrils, the proliferation of cancer cells was suppressed. Furthermore, Akt activation, which is known as a cell-survival signal, was inhibited in cells on collagen fibrils. But the activation of ERK1/2 was not completely inhibited. In Caco-2 cells, delay of cell cycle progression and cell death occurred at the same time. Thus, cell division and cell death occurred at equivalent rates on the collagen fibrils, and cell growth seemed to be stopped. These results imply that the fibril form of collagen plays a potential role in inhibiting the growth of cancer cells.
