What is a breast acinus?
The luminal cells of acini are arranged radially with tight junctions between cells located at the narrow width of the cells, near the central lumen (see Fig. 1). The primary function of the acinus is milk secretion. Milk flow into the ducts is powered by the contractions of the myoepithelial cells.
