Generation of fibroblast-like cells from cloned epithelial mammary cells in vitro: a possible new cell type

R Dulbecco et al. Proc Natl Acad Sci U S A. 1981 Apr.

Abstract

We have isolated clonal cell lines from a nitrosomethylurea-induced mammary tumor in Wistar--Furth rats. The epithelial-like cells of these lines give rise to fibroblast-like cells. A study of several markers showed that the epithelial-like cells are similar to epithelial mammary cells. The fibroblastic cells, however, were similar to stromal cells, except for the production of collagen IV. The events occurring in these cultures are identical to those observed in previously isolated mammary cultures [Bennett, D. C., Peachey, L. A., Durbin, H. & Rudland, P. S. (1976) Cell 15, 283--298], suggesting their generality. The fibroblast-like cells generated in culture may be a hitherto unrecognized type of mammary cell.
