移植瘤在最初的6天左右是依赖组织液生长,以后因肿瘤细胞分泌“促血管生长因子”(TAF),促使周围血管向瘤体长出毛细血管,当毛细血管长入肿瘤组织以后,瘤体就迅速生长。可的松是抗炎症药物,能抑制血管内皮细胞分裂,也有使转化细胞表型逆转的作用,但在整体动物大剂量持续使 The transplanted tumors depend on the growth of the tissue fluid in the first 6 days or so. After that, the tumor cells secrete an “angiogenic growth factor” (TAF), which causes the surrounding blood vessels to grow capillaries into the tumor. When the capillaries grow into the tumor tissue, the tumor body It grows quickly. Cortisone is an anti-inflammatory drug that inhibits the division of vascular endothelial cells and also has the effect of reversing the phenotype of transformed cells, but continues to be used in large doses throughout the animal.
