A system for the primary serum-free culture of fetal rat gastrointestinal epithelial cells was used to examine the role of the extracellular matrix (ECM) in the attachment and proliferation of these epithelial cells. Forestomach epithelial cells (FSEC) were able to attach to and proliferate on plastic dishes without a substratum, while glandular stomach epithelial cells (GSEC) and duodenal epithelial cells (DEC) were unable to do so. The presence of a substratum promoted the attachment and proliferation of these epithelial cells. The effects of various components of the ECM differed depending on the type of cell. FSEC attached most efficiently to a substratum of fibronectin, while GSEC did so to laminin. DEC attached more efficiently to type I collagen and fibronectin than to any other substratum. FSEC proliferated most rapidly on laminin, while GSEC and DEC did so on collagen gels. These substrata induced the most efficient attachment and proliferation of FSEC, and they were effective in promoting the attachment and proliferation of GSEC and DEC in decreasing order of efficiency, indicating the existence of a head-to-tail gradient in the response of epithelial cells to substrata. The expression of c-myc mRNA in these cells differed depending upon the substratum on which they were cultured and the mRNA level was well correlated with the extent of the cell proliferation, indicating that the cell proliferation is mediated by c-myc gene expression, which is regulated by cell-ECM interactions. The results of the present study demonstrate that proliferation of gastrointestinal epithelial cells is regulated region-specifically not only by soluble factors but also by insoluble components of the ECM.
