Pancreatic polypeptide (HPP) producing cells were detected in 23 out of 36 endocrine tumours of the pancreas. In all tumours shown to be producing two hormones it was possible to demonstrate two different cell types by immunocytochemistry and/or electron microscopy. The D1 cell was identified as the source of HPP in tumours.
在36例胰腺内分泌肿瘤中，有23例检测到产生胰多肽（HPP）的细胞。在所有显示产生两种激素的肿瘤中，通过免疫细胞化学和/或电子显微镜有可能证实存在两种不同的细胞类型。在肿瘤中，D1细胞被确定为HPP的来源。
