我们研究了胸腺上皮细胞和未成熟胸腺细胞表达的E-钙粘蛋白在胸腺器官发生和胸腺细胞发育中的作用。ECCD-1单克隆抗体,阻断同型E-钙粘蛋白的相互作用,抑制上皮组织和胸腺细胞的发展,在重新聚集胎儿胸腺器官培养。它也干扰了脱氧鸟苷处理的胸腺叶内的胎儿肝细胞或胎儿胸腺细胞的分化,但不影响完整培养的胎儿胸腺叶中胸腺细胞的发育。相反,选择性抑制E-cadherin和αEβ 7整合素之间相互作用的抗体不会干扰胸腺上皮组织或胸腺细胞发育,表明同型E-cadherin相互作用在胸腺发育和功能中起重要作用。
We examined the role of E-cadherin expressed by thymic epithelial cells and immature thymocytes in thymus organogenesis and thymocyte development. ECCD-1 MAb, which blocks homotypic E-cadherin interactions, inhibited epithelial organization and thymocyte development in reaggregate fetal thymic organ cultures. It also interfered with the differentiation of fetal liver cells or fetal thymocytes within deoxyguanosine-treated thymic lobes, but did not affect thymocyte development in intact cultured fetal thymic lobes. In contrast, antibodies that selectively inhibit interactions between E-cadherin and αEβ7integrins did not perturb thymic epithelial organization or thymocyte development, suggesting that homotypic E-cadherin interactions play an important role in thymus development and function.
