Abstract

We report the isolation of eight independent cell lines from preimplantation mouse embryos, which have a parietal endoderm phenotype. When grown as aggregates, these cell lines produce large amounts of a basement membrane matrix, that contains laminin, nidogen, heparan sulfate proteoglycan, collagen IV, and BM-40. The biosynthetic profiles of all eight cell lines are very similar to parietal endoderm cells in vivo which synthesize Reichert's membrane. The structure of the matrix produced by the parietal endoderm cell lines (PEC lines) resembles more closely Reichert's membrane than the Engelbreth-Holm-Swarm (EHS) tumor in susceptibility to proteolytic degradation. Since these cell lines produce large quantities of basement membrane they will be useful for structural and functional comparison of a Reichert's membrane matrix with the basement membrane produced by the EHS tumor.
