Cells of the intercalary ducts showed concentrations of secretory granules adjacent to the luminal plasma membrane. Evidence of thiamine-pyrophosphatase activity was seen in the Golgi apparatus and of acid-phosphatase activity in GERL-like structure, lysosomes and immature secretory granules. Adenosine-triphosphatase reaction-product was present along surfaces of myoepithelial cells and to a lesser extent along contiguous surfaces of duct cells. The findings indicate secretory activity in the intercalary duct cells.
闰管细胞显示分泌颗粒集中于管腔质膜附近。在高尔基体中可见硫胺素焦磷酸酶活性的证据，在类GERL结构、溶酶体和未成熟分泌颗粒中可见酸性磷酸酶活性的证据。三磷酸腺苷酶反应产物存在于肌上皮细胞表面，在较小程度上也存在于导管细胞的相邻表面。这些发现表明闰管细胞具有分泌活性。
