Tweetable abstract Tumor-associated macrophages might promote the distant metastasis of tumor cells by semi-phagocytosis. The authors propose that this newly discovered process occurs in tumor-associated macrophages and may lead to a novel approach for blocking cancer metastasis.
Keywords: aging macrophages; cancer metastasis; circulating tumor cells; premetastatic niches; semi-phagocytosis; tumor-associated macrophages.
