Present studies reported direct evidence of anti-migration factor secreted from growing tumor in vivo ard in vitro which could be counteracted by virus. In mice transplanted ip with S180, Ehrlich or P388 ascitic tumor cells, the number of Mφs decreased very rapidly. The che-motaxis of Mφs to the tumor site(peritoneal cavity) occurred rapidly when PRs virus was given ip. Supernatants of ascites fluid from S180 or tissue culture fluids from BTAB, HeLa or Hep2 tumor cells depressed the migration of Mφbut not tissue culture fluid from primary hamster kidney cell, rabbit kidney cell or human diploid cell culture. The addition of virus to tissue culture fluid of Hep2 cells led to a great increase of chemotaxis.

本文报告了一些体内肿瘤和体外瘤细胞分泌的抗巨噬细胞移动因子。小鼠腹腔移植S_(180)、Ehrlich或P_(388)腹水瘤细胞后,巨噬细胞迅速减少,并在PR_8病毒腹腔注射后巨噬细胞迅速移至腹腔。体外BTAB、HeLa、Hep-2细胞的组织培养液能抑制巨噬细胞的移动,而正常组织培养液则不能,提示抗巨噬细胞移动因子可能由肿瘤细胞分泌。
