Abstract |
Type V collagen is one of the minor components of the extracellular matrix (ECM) whose content is increased in cases of ductal infiltrating carcinomas of the breast. In order to clarify its biological role, we have investigated the effect of this molecule, both as substrate and as soluble factor, on the behaviour of a breast carcinoma cell line (8701-BC) grown in vitro. Cell- collagen adhesion was monitored for 24 h from plating in the absence or presence of serum. The influence of type V collagen on cell growth was followed during 9 days of culture, and the actin- vinculin arrangement was studied by simultaneous fluorescent immuno-staining. The results indicate that type V collagen is not a permissive substrate for neoplastic cell proliferation and dissemination in vitro.
