Abstract (original English)
The mammary gland develops from the placode at ectodermal invagination. The rudimentary parenchyma (mammary bud) develops mammary trees and alveolar structures, suggesting that the mammary bud consists of stem/progenitor cells. Here, we established a clonal stem cell line from a mammary bud of a p53 null female embryo at day 14.5. FP5-3-1 line was a homogeneous cell population with polygonal epithelial morphology and spontaneously became heterogeneous during passages. Recloning gave rise to four sublines; three sublines have basal epithelial property and one subline has luminal epithelial property. The former sublines generate functional mammary glands when injected into cleared fat pads and the latter subline does not. The cell lines also express many stemness-related genes. The clonal cell lines established in the present study are shown to be mammary stem cells and not tumorigenic. They provide useful models for normal and tumor biology of the mammary gland in vivo and in vitro.
