人类胰腺最常见的癌瘤——导管细胞癌,通常被认为是源自导管细胞的。这种推测的主要依据是肿瘤细胞的形态与导管细胞相似,且细胞缺乏酶原颗粒或者在胞浆中出现粘液。以含有胞浆颗粒的形态学标准诊断的腺泡细胞癌是少见的,约占所有胰腺癌的1～ The most common carcinoma of the human pancreas, ductal cell carcinoma, is usually thought to originate from ductal cells. The main reason for this speculation is that the morphology of tumor cells is similar to that of ductal cells, and the cells lack zymogen particles or mucus in the cytoplasm. Acinar cell carcinoma diagnosed with morphological criteria containing cytoplasmic granules is rare and accounts for approximately 1 to 1 of all pancreatic cancers.
