Objective To establish the primary culture of aldosterone-producing adenoma cells. Methods The tumor tissue was digested by collagen type I and cultured in complete DMEM/F12 medium. Aldosterone concentra-tion in culture medium was detected by radioimmunoassay. The expression of aldosterone synthase in the culture cells was detected by immunofluorescence. Results Aldosterone-producing adenoma cells grew adherently in a round or approximately round shape. The cells were positively immunostained for aldosterone synthase. The aldoste-rone concentration in the culture medium at the 5th culture day was (30.0±8.9)nmol/L. During the primary cul-ture,aldosterone secretion was the strongest at the first day,and decreased afterwards. It kept stable from day 4 to 11. Conclusions We successfully established the primary culture of aldosterone-producing adenoma cells, which are important for the future studying on the mechanism and function of aldosterone-producing adenoma.%目的 建立醛固酮瘤的原代细胞培养方法并进行细胞鉴定.方法 用Ⅰ型胶原酶把人醛固酮瘤组织消化成单个细胞后进行培养;用放免法测定培养液中醛固酮浓度,用免疫荧光法检测细胞内醛固酮合成酶表达.结果 原代培养的人醛固酮瘤细胞贴壁增殖,大部分细胞呈圆形,有醛固酮合成酶表达.原代培养第5天,培养液中醛固酮水平为(30.0±8.9) nmol/L.醛固酮瘤细胞培养第1天分泌醛固酮的功能最强,此后逐渐减弱,在第4~11天细胞分泌功能基本不变.结论 成功建立了醛固酮瘤细胞的原代培养方法,有利于今后对醛固酮瘤的发病机制及功能研究.
