由于成纤维细胞生长因子10 (FGF-10)基因表达可能在肛肠管形成过程中发挥作用,本研究旨在评估FGF-10在人胚胎直肠和后肠发育过程中的时空表达模式。在使用FGF-10特异性抗体进行免疫组化评估后,在妊娠3-8周的人类胚胎(n = 85)中评估FGF-10的表达。从妊娠第4 - 7周,FGF-10主要在尿直肠隔背侧、阴道膜(CM)和后肠的顶端上皮中表达。CM破裂后(第7周),肛管上皮FGF-10呈阴性;然而,在第7周,它一直存在于尿路上皮内。在人后肠和肛肠发育过程中FGF-10的表达表明它可能在后肠和肛肠形态发生中发挥作用。
As fibroblast growth factor 10 (FGF-10) gene expression may have a role in anorectal duct formation, this study aimed to assess the spatiotemporal expression pattern of FGF-10 during development of the rectum and hindgut in human embryos. FGF-10 expression was evaluated in human embryos (n = 85) at 3-8 weeks of gestation after immunohistochemical evaluation using antibodies specific for FGF-10. From weeks 4 to 7 of gestation, FGF-10 expression was observed primarily in the apical epithelium of the dorsal urorectal septum, the cloacal membrane (CM) and the hindgut. Following CM rupture (week 7), the epithelium of the anal canal was negative for FGF-10; however, it was present within the urothelium through week 7. FGF-10 expression during the development of the human hindgut and anorectum suggests that it may play a role in hindgut and anorectal morphogenesis.
