Abstract　： [Introduction] It is known that the submandibular gland in rodents has different component cells between the adult and juvenile periods. The end portion of the gland is called the terminal tubule which is composed of an immature secretory unit. The terminal tubule has three different cells - the acinar cell, the proacinar cell and the terminal tubule cell. The proacinar cell is the precursor of the acinar cell, and it is known that all of the proacinar cells differentiate into the acinar cell by the second week after birth. Although the terminal tubule cell is the one which is recognized the most in the submandibular gland of the juvenile period, it does not exist in the adult submandibular gland. Yohro has reported that the granular intercalated duct cell, which is recognized in the submandibular gland of adult mouse, is the surviving remnant of the terminal tubule cell. Hayashi et al. have reported that three different staining characteristics can be recognized as the terminal tubule cell varies in secretory activity.
