Potential uses of milk epithelial cells: a review.
Secretions collected from the mammary gland of different species contain heterogeneous populations of cells including lymphocytes, neutrophils, macrophages and epithelial cells in different species. Several factors influence the somatic cell count in milk and the distribution of cell types, such as species, infection status, physiological status and management practices. The epithelial cells are shed into milk during the lactation process. Most of them are viable and exhibit the characteristics of fully differentiated alveolar cells. Primary cultures of epithelial cells from colostrum and milk of humans, baboons, cows and goats together with established cell lines from human and goat milk, provide a good model for the study of lactogenesis, immunity transmission, cancer research and infection by viruses. The RNA extracted from milk cells have been shown to be representative of gene expression in the mammary gland and thus provide a source of material for molecular studies of gene expression and environmental interactions.
