The rat parotid gland--a renewing cell population.
The mode of turnover and displacement of cells in the rat parotid gland was studied by means of autoradiography. The parotid parenchyma and stroma act as a two-compartment cell renewal system. Parotid cell progenitors are formed mainly in the intercalated duct from which they progress in opposite directions: to the striated duct on one side, while feeding into the acini on the other. The stroma cells stream along the same tissue radii as the parenchymal cells.
