肿瘤基质肌纤维母细胞反应,是宿主对肿瘤的第三反应。它能增加肿瘤间质的密度和收缩性,限制瘤细胞移行入血管腔及神经周围间隙,延缓肿瘤浸润过程。因而引起人们兴趣。但至今有不少问题尚未探明。本文拟通过对乳腺癌和胄腺癌基质肌纤维母细胞的组织学和超微结构观察,结合临床资料探讨下列问题:(1)肿瘤基质中肌纤维母细胞的来源;(2)基质肌纤维母细胞在不同部位 The tumor stromal myofibroblast response is the third response of the host to the tumor. It can increase the density and contractility of the tumor stroma, limiting the migration of tumor cells into the lumen of the blood vessels and around the nerves, delaying the process of tumor invasion. This caused people’s interest. However, many problems have not yet been discovered. This article intends to investigate the histological and ultrastructural observations of mammary adenocarcinoma of the breast and parotid adenocarcinoma, combined with clinical data to explore the following issues: (1) the origin of myofibroblasts in the tumor stroma; (2) the matrix muscle fibroblasts Different parts
