将艾氏腹水癌细胞接种于小鼠脚掌皮内,30分钟内癌细胞以单个散在的形式到达腘窝淋巴结,3小时内到达髂动脉旁淋巴结,瘤细胞先停留在包膜下边缘窦,然后到中间窦及髓窦,增殖后形成转移灶。于40天时,可在多处淋巴结内形成多发性转移灶。同时于引流淋巴结内出现一系列增生性反应。在淋巴结副皮质区内出现大量形态不同、具有伪足的活动型小淋巴细胞,其形态与毛细血管后小静脉壁内内皮细胞间所经常看到的游走小淋巴细胞相似,其意义尚不清楚。
Ehrlich ascites cancer cells were inoculated into the paw of the mouse. Within 30 minutes, the cancer cells reached the axillary lymph node in a scattered form and reached the para-aortic lymph node within 3 hours. The tumor cells first stayed in the subcapsular marginal sinus, and then To the middle sinus and spinal sinus, proliferation after the formation of metastases. At day 40, multiple metastases can form in multiple lymph nodes. At the same time, a series of proliferative reactions occur in the draining lymph nodes. In the lymphoid paracortex, there are a large number of active small lymphocytes with different morphology and pseudopodia. Their morphology is similar to that of migratory small lymphocytes often seen in endothelial cells in the posterior wall of capillaries behind the capillaries. clear.
