卵巢和垂体激素在乳癌的病因学上具有重要地位,其中研究最广的是雌激素和催乳素,两者皆能促进(齿聂)齿类动物实验性乳癌的生长速度。实验表明,无胸腺小鼠可用于研究体液因素对人体乳癌细胞的影响。实验选用两类癌细胞株,一株为原发于大鼠垂体的无性细胞瘤(GH_3),给无胸腺小鼠注射作为外源性垂体因子的供体。一株为人乳癌细胞(T-47D),取自 Ovarian and pituitary hormones play an important role in the etiology of breast cancer, with estrogen and prolactin being the most widely studied, both of which promote the growth of experimental breast cancers in tooth dentition. Experiments show that athymic mice can be used to study the impact of body fluids on human breast cancer cells. Two types of cancer cell lines were selected for experiment. One was a dysplastic aneurysm (GH_3) derived from the pituitary of rats. Athymic mice were injected with a donor of exogenous pituitary factor. A strain of human breast cancer cells (T-47D), taken from
