Abstract

During the development of the rat mammary gland, ducts are formed from end-buds, which contain the stem cells. In this process a lumen is formed in the semisolid mass of the end-bud, and the cells acquire polarity. We have studied this process by following the localization of three inframembranous proteins present in the cells of both end-buds and ducts: microvillin, the microvillar protein p80, and the desmosomal plaque protein p205. We find that the development of ducts is accompanied by a redistribution of these proteins, which in immature parts of the end-buds are found together in the cell. Microvillin and p80 go together to the apical pole of the cells, in contact with the lumen, whereas p205 goes to the basal surface, in contact with cells of the myoepithelial lineage. The acquisition of polarity occurs at the same time as a lumen begins to form by local gaps between cells. It seems likely that the redistribution of the inframembraneous proteins is the consequence of the localization of surface glycoproteins that affect in opposite ways the adhesion between the cells.
