title: [Observation of proliferative capacity of rat salivary gland cells].
abstract: Proliferative potentiality of adult rat salivary gland cells was studied by means of bromodeoxyuridine (BrdU) labeling in different time and ABC immunohistochemistry. The labeling rate of intercalated cells in different time after BrdU injection manifest the character of stem cell which is concordant with the theory of semipluripotential bicellular reserve cell suggested by Eversole and Batsakis. This initial labeling rate of intercalated cell is very low and it rises very rapidly to 78 times within 5 days. On the other hand, it also goes down very fast. We proved that the acinar cells and striated cells have the capacity of proliferation which is not so high as intercalated cells for self renewal that can complete the theory of semipluripotential bicellular reserve cell and is beneficial to explain why there is a variety of salivary gland neoplasms.
