总结用电子显微镜研究的肝硬化的活组织检查显示在纤维组织中存在修饰的成纤维细胞(“肌成纤维细胞”)。这些细胞具有平滑肌细胞和成纤维细胞的形态特征。在药理学研究中,其他工作者已经表明,在各种血管活性剂的影响下,具有这些细胞的愈合伤口的肉芽组织条以平滑肌的方式收缩。这表明,这种收缩细胞的存在下,在瘢痕中的肝硬化可能是一个重要的贡献因素,在门静脉高压症的发病机制和进展的硬化过程。
Summary Biopsies of cirrhotic livers studied with the electron microscope showed the presence of modified fibroblasts (‘myofibroblasts’) in the fibrous tissue. These cells share the morphological characteristics of smooth muscle cells and fibroblasts. In pharmacological studies other workers have shown that strips of granulation tissue from healing wounds possessing such cells contract under the influence of various vaso‐active agents in the manner of smooth muscle. It is suggested that the presence of such contractile cells in the scars in cirrhotic livers may be an important contributing factor in the pathogenesis of portal hypertension and the progression of the cirrhotic process.
