Summary

We compared the growth and morphology of normal, dysplastic and malignant human mammary epithelial cells (HMEC) in medium containing 5% human serum, a serum-free medium (32) and serum-free medium with a low Ca++ concentration. Tissues were dissociated and epithelial organoids or single cells were seeded onto collagen-coated dishes. The cells grew in serum-containing medium, but growth of fibroblasts was also stimulated. The serum-free medium consistently selected for and stimulated the growth of epithelial cells. There was little advantage in reducing the Ca++ concentration to further increase cell yield. This serum-free primary culture system allows us to routinely prouce sufficient numbers of HMEC from small tissue samples for molecular biological investigations. Furthermore, the maintenance of cells in a defined medium can provide a system for evaluating the direct effects of factors on gene expression.
