小鼠的人体移植瘤保持人体肿瘤形态和功能特征，表现型和遗传型都与原发性肿瘤相似，是最接近于人类肿瘤的实验模型，目前已在肿瘤学和免疫学等研究领域中广泛应用。本研究采用人胃癌组织及S；。。腹水瘤细胞接种于小鼠皮下，鼠间传代建立小鼠移植瘤模型，并采用He－Ne激光照射 Human transplanted tumors in mice maintain the morphological and functional characteristics of human tumors. Both phenotype and heritability are similar to those of primary tumors. They are the closest to human tumor models and have been widely used in research fields such as oncology and immunology. application. This study used human gastric cancer tissue and S;. . Ascites tumor cells were inoculated subcutaneously in mice and mice were transplanted to establish a mouse xenograft model and He-Ne laser irradiation was used.
