DEVELOPMENT OF DUCTAL CELL CULTURE FROM PAROTID GLAND

提出的研究目标是开发和评估未转换的 大鼠腮腺导管细胞培养的实验研究 发生的生理和病理生理学变化的体外研究 在外分泌腺细胞中。目标将是长期的文化 导管细胞和这些细胞的传代，从而使细胞 可用于比急性实验更长时间的研究。因为 细胞在培养中趋于去分化，导管细胞将被分离 从分散的细胞制剂中分离出来的 有其特有的形态特征。导管细胞将被分离并 进行生化分析以获得基线数据。大鼠腮腺有 之所以被选中进行这些研究，是因为大多数管道是 纹状管(Redman，1987；Robinovitch，1967)和纹状管是重要的 对电解质的调节(Schneyer等人，1972)。孤立导管 细胞将生长在基底膜涂层培养皿中。这个 由此产生的培养物将具有形态和生化特征。 为了确保培养中的细胞是起源于导管的， 将使用导管细胞标记物。

The goal of the research proposed is to develop and evaluate nontransformed ductal cell cultures of rat parotid glands to be used as models for the in vitro study of the physiological and pathophysiological changes that occur in exocrine gland cells. The objective will be the long-term culture of ductal cells and the passaging of these cells, thereby making cells available for study over a longer period than an acute experiment. Because cells tend to dedifferentiate in culture, ductal cells will be isolated from dispersed cell preparations prior to culturing while the cells still have their characteristic morphology. Ductal cells will be isolated and analyzed biochemically to obtain baseline data. The rat parotid gland has been chosen for these studies because the majority of the ducts are striated (Redman, 1987; Robinovitch, 1967) and striated ducts are important in regulation of electrolytes (Schneyer et al., 1972). Isolated ductal cells will be grown in basement membrane coated culture dishes. The resulting cultures will be morphologically and biochemically characterized. To insure that the cells in culture are ductal in origin, antibodies to ductal cell markers will be used.
