Abstract

Morphological and functional changes in human monocytes and peritoneal macrophages from six patients with ovarian cancer were studied. The surface architecture of exudate macrophages from ascitic fluid have already been shown to exhibit extensive spreading and ruffled membranes. Consequently, peripheral monocytes from the patients were cultured with ascitic fluid from the same individuals. They gradually displayed active membrane pseudopodia, thorn-like processes and petal-like ruffles after 2 h to 4 h of cultivation. Adherent peritoneal macrophages from the patients demonstrated increased consumption of glucose. These results suggest a macrophage activating factor (MAF) exists in ascitic fluid in patients with ovarian cancer which plays an initial role in the change of monocytes into macrophages.

摘要

对6例卵巢癌患者的人单核细胞和腹腔巨噬细胞的形态学和功能变化进行了研究。来自腹水的渗出性巨噬细胞的表面结构已显示出广泛的铺展和皱襞膜。因此,将患者的外周单核细胞与来自同一患者的腹水一起培养。培养2至4小时后,它们逐渐显示出活跃的膜伪足、刺状突起和花瓣状皱襞。患者的贴壁腹腔巨噬细胞显示出葡萄糖消耗增加。这些结果表明卵巢癌患者腹水中存在巨噬细胞活化因子(MAF),其在单核细胞向巨噬细胞的转变中起初始作用。
