已有研究表明肿瘤组织中存在着不同数量的免疫活性细胞，并可对相邻的瘤细胞产生杀伤作用。笔者在研究肾母细胞瘤组织浸润淋巴细胞抗肿瘤效应的同时，观察到瘤细胞间存在着少数巨噬细胞，为了解两者之间的关系，现报告如下。方法12例肾母细胞瘤新鲜标本，离体后迅速切取3－4块1
Studies have shown that there are different numbers of immunocompetent cells in tumor tissue and can kill adjacent tumor cells. While investigating the anti-tumor effect of nephroblastin infiltrating lymphocytes, we observed a few macrophages exist between tumor cells. To understand the relationship between the two, we report the following. Methods Twelve nephroblastoma samples were freshly harvested and isolated in vitro
