利用微孔膜支持物铺以细胞外介质体外培养金黄地鼠腮腺腺细胞．细胞单层生长，呈立方状或柱状，体外可维持２个月．细胞连接处形成皱折，含较多微绒毛，底部与细胞外介质相连．胞膜、胞核与细胞器是极性分布可区分腺泡细胞，导管上皮以及肌上皮细胞。说明，在此条件下，腮腺腺细胞在结构上建立了细胞极性，保留了腺泡导管分泌单位的上皮细胞特点． In vitro culture of hamster parotid gland cells with extracellular medium using microporous membrane support. Monolayer growth, was cubic or columnar, in vitro can be maintained for 2 months. Collapsing at the cell junction, with more microvilli, is connected to the extracellular matrix at the bottom. The membrane, nucleus and organelles are polar distributions that distinguish acinar cells, ductal epithelium, and myoepithelial cells. This shows that in this condition, the parotid gland cells in the structure of the establishment of cell polarity, leaving the acinar duct secretion of epithelial cells.
