目的 建立簡(jiǎn)單、有效而穩(wěn)定的大鼠肝臟Kupffer細(xì)胞分離、純化的實(shí)驗(yàn)方法。
方法 ?、俅笫蟾闻K的膠原酶離體灌注； ②Percoll液不連續(xù)梯度離心分離Kupffer細(xì)胞； ③選擇性貼壁純化Kupffer細(xì)胞； ④吞噬墨汁實(shí)驗(yàn)、DAB染色，光鏡、電鏡下觀察鑒定Kupffer細(xì)胞。
結(jié)果 最終獲得的大鼠肝臟Kupffer細(xì)胞活性 gt;90%，純度為95%，光鏡下Kupffer細(xì)胞具有較強(qiáng)的貼壁及吞噬碳粒能力，DAB染色呈黃色煎蛋樣結(jié)構(gòu)； 新分離的Kupffer細(xì)胞呈圓形，形態(tài)大小一致； 2 d后，細(xì)胞發(fā)生伸展，呈多角形或星形。電鏡下觀察可見(jiàn)典型特點(diǎn)： 有偽足及杯口狀改變，有豐富的溶酶體和吞噬體。
結(jié)論 本實(shí)驗(yàn)建立的大鼠肝臟Kupffer細(xì)胞的分離培養(yǎng)方法效果穩(wěn)定，同時(shí)培養(yǎng)的細(xì)胞具有良好的生物學(xué)性狀。
