纤维调素(FMOD)是一种细胞外基质(ECM),富含亮氨酸的蛋白多糖(SLRP),在决定细胞命运中起着重要作用。先前的研究表明,FMOD不仅在胎儿类型的无疤痕伤口愈合中至关重要,而且它还促进成人伤口的闭合和减少疤痕的形成。此外,FMOD缺陷小鼠在伤口愈合过程中肉芽组织中的血管再生显著减少。在这项研究中,我们研究了FMOD对血管生成的影响,血管生成是伤口愈合以及胚胎发育和肿瘤发生的重要事件。我们发现,FMOD在体外加速了人脐静脉内皮细胞HUVEC-CS细胞的黏附、铺展、肌动蛋白应激纤维的形成,最终形成管状结构(TLS)网络。在分子水平上,FMOD通过增加I型和III型胶原、血管生成素(Ang)-2和血管内皮生长因子(VEGF)的表达,以及降低Ang-1/Ang-2的比例,为动员静止的内皮细胞向血管生成表型提供了有利的网络。此外,我们还通过体内鸡胚绒毛尿囊膜(CAM)实验证实了FMOD促进了体内血管生成。因此,我们的数据表明,FMOD是一种促血管生成的药物,并提示FMOD在治疗与血管生成受损相关的疾病方面具有潜在的治疗作用。
Fibromodulin (FMOD) is an extracellular matrix (ECM) small leucine-rich proteoglycan (SLRP) that plays an important role in cell fate determination. Previous studies revealed that not only is FMOD critical in fetal-type scarless wound healing, but it also promotes adult wound closure and reduces scar formation. In addition, FMOD-deficient mice exhibit significantly reduced blood vessel regeneration in granulation tissues during wound healing. In this study, we investigated the effects of FMOD on angiogenesis, which is an important event in wound healing as well as embryonic development and tumorigenesis. We found that FMOD accelerated human umbilical vein endothelial HUVEC-CS cell adhesion, spreading, actin stress fiber formation, and eventually tube-like structure (TLS) network establishment in vitro. On a molecular level, by increasing expression of collagen I and III, angiopoietin (Ang)-2, and vascular endothelial growth factor (VEGF), as well as reducing the ratio of Ang-1/Ang-2, FMOD provided a favorable network to mobilize quiescent endothelial cells to an angiogenic phenotype. Moreover, we also confirmed that FMOD enhanced angiogenesis in vivo by using an in ovo chick embryo chorioallantoic membrane (CAM) assay. Therefore, our data demonstrate that FMOD is a pro-angiogenic and suggest a potential therapeutic role of FMOD in the treatment of conditions related to impaired angiogenesis.
