  • Title: Serum-free primary culture of normal mouse mammary epithelial and stromal cells.
    Author: Wang S, Haslam SZ.
    Journal: In Vitro Cell Dev Biol Anim; 1994 Dec; 30A(12):859-66. PubMed ID: 7534593.
    Abstract:
    An in vitro serum-free culture system provides an important approach to the understanding of local hormonal regulation of mammary epithelial and fibroblast cells, avoiding the complexity of the in vivo environment and the influence of undefined serum factors. The substratum conditions and medium components have been examined for the basal growth of epithelial cells, fibroblasts, and combined epithelial and fibroblast cells in monolayer cultures. Epithelial cells and mixed cells exhibit good attachment and maintenance on a collagen-coated surface in a minimal medium supplemented with fetuin and insulin. In contrast, fibroblast-enriched cultures require a plastic substratum and a medium supplemented with insulin, fetuin, and hydrocortisone. In mixed cell culture, fibroblasts are maintained well in the minimal media which supports the maintenance of epithelial cells. These results indicate that the presence of epithelial cells in mixed cell cultures can influence fibroblast function. The media developed in the present study can be used in future studies of fibroblast and epithelial cell interactions with regard to hormone and growth factor regulation of their growth and differentiation.
