Identification of Stem Cells in the Secretory Complex of Salivary Glands.

ABSTRACT: Salivary glands have an essential secretory function for maintaining oral and overall health. The epithelial compartment of the gland is composed of several highly specialized cell types that cooperate to secrete and deliver saliva to the oral cavity. The mouse submandibular gland has been used as a model for major salivary glands in human. The secretory complex in this model is composed of 2 secretory compartments, including acini and granular ducts connected by intercalated ducts. Contractile myoepithelial cells surround the secretory complex to facilitate salivary flow. Whether differentiated cells in the secretory complex are maintained by self-duplication or contribution from stem cells has remained an open question. Here, in analyzing the expression of basal cytokeratin (K) 14 in the
