Chief cells make and secrete pepsinogen.

主细胞制造和分泌胃蛋白酶原。

Objective To explore the clinical significance of serum pepsinogen subtypes measurements for the diagnosis of stomach lessions.

目的探讨血清胃蛋白酶原亚群测定对胃部疾病的诊断意义。

METHODS: The method of immunohistochemistry was used to examine the expression of pepsinogen C in 318 cases of stomach mucosa;

方法：采用免疫组织化学染色法检测318例胃黏膜标本中胃蛋白酶原C的表达情况；

The impressively named chief cells secrete pepsinogen which, when it mixes with stomach acid, becomes an enzyme called pepsin.

而令人印象深刻的主细胞则分泌胃蛋白酶原，当它与胃酸混合时，就形成一种酶，叫做胃蛋白酶。
