通过对３８例胃肠道印戒细胞癌进行超微细胞结构观察，发现印戒细胞癌可有三种类型，即粘液型、微囊型和糖原型。结合粘液组化染色，作者对印戒细胞癌的细胞起源以及癌细胞不同形态表现的原因和意义进行了探讨，认为印戒细胞癌起源于具有多潜能分化的干细胞，癌细胞超微结构形态特征的变化是其畸形分化或功能代谢不同的具体表现。
By observing the ultrastructure of 38 cases of signet-ring cell carcinoma of the gastrointestinal tract, it was found that there are three types of signet-ring cell carcinoma, namely mucinous type, microcapsule type, and sugar prototype. Combining mucin histochemical staining, the authors discussed the origin of the signet ring cell carcinoma and the causes and significance of the different morphological manifestations of the cancer cells. It is believed that signet-ring cell carcinoma originates from stem cells with multipotential differentiation, and the ultrastructure of cancer cells The change is the specific manifestation of its abnormal differentiation or functional metabolism.
