An immunoperoxidase technique has been used to localise clotting factor XIII subunits A and S in human tissues. The presence of factor XIII in placenta and megakaryocytes was confirmed. Factor XIII was also found in fibroblasts, a hitherto unreported finding. Factor XIII subunits were not detected in hepatocytes, although factor XIII was found in fibroblasts in portal tracts. These findings suggest that factor XIII is not synthesised in the liver as previously thought.
已采用免疫过氧化物酶技术在人体组织中定位凝血因子 XIII 的 A 亚基和 S 亚基。证实了胎盘和巨核细胞中存在因子 XIII。在成纤维细胞中也发现了因子 XIII,这是迄今未报道的发现。尽管在门管区的成纤维细胞中发现了因子 XIII,但在肝细胞中未检测到因子 XIII 亚基。这些发现表明,因子 XIII 并非如先前认为的那样在肝脏中合成。
