The effects of type I and IV collagens on the survival and proliferation of cells were investigated to clarify a possible involvement of the substratum in the regulation of cell function. BSC-1 cells attached, spread and sustained their viability in the absence of calf serum on culture dishes coated with type IV collagen, but were unable to spread and survive on untreated culture dishes. The effects of adding type IV collagen in solution were similar to those of type IV coating. The fraction of the solution of type IV collagen with molecular mass of more than 100 kDa enhanced spreading and survival of cells, but the fraction of less than 100 kDa did not. Type I collagen did not support cell viability in the absence of calf serum. Moreover, coating of culture dishes with type I collagen, but not with type IV collagen, inhibited DNA synthesis and cell proliferation in the presence of calf serum. The cells grown on type I collagen were long, thin and spindle-shaped, and their stress fibers were not well developed, but the cells grown on type IV collagen, as well as those grown on untreated culture dishes, were polygonal in shape with well-developed stress fibers. These results indicate that the interactions of BSC-1 cells with the substratum, when it is derived from type I and IV collagens, differentially modulate the survival and proliferation of BSC-1 cells.
