    【目的】探讨原代培养垂体腺瘤的细胞纯化方法及其激素表达与分泌的特点。【方法】采用三种原代培养方法对垂体腺瘤细胞进行培养,方法Ⅰ为目前常用的垂体瘤细胞培养方法,方法Ⅱ结合使用右旋颉氨酸(D-valineDMEMD-valine)培养液,方法Ⅲ采用反复贴壁法结合DMEMD-valine培养液培养。观察其细胞形态变化和生长特征,放射免疫法测定不同培养时间培养液中相应激素的水平。免疫组织化学染色法检测培养细胞生长激素(growthhormone,GH)、泌乳素(prolactin,PRL)的表达。【结果】3种方法均能成功培养出垂体腺瘤细胞,呈圆形或椭圆形,其纯度随培养时间的延长逐渐下降,培养第20天其平均纯度分别为40%,46%,96%。方法Ⅲ明显高于方法Ⅰ和方法Ⅱ,差异具有显著性意义(P〈0.01);培养液中均含有相应激素。且3种方法的激素分泌量没有统计学差异(P〉0.05);腺瘤细胞分别呈GH,PRL阳性表达,成纤维细胞表达Ⅰ型胶原。【结论】方法Ⅲ可得到纯度达95%以上的人垂体腺瘤细胞,纯化后的细胞可分别呈GH和PRL阳性表达并具有良好的激素分泌功能,为进一步研究人垂体腺瘤的发病机理、药物治疗和颅外移植等方面奠定了实验基础
