The paradigm of an extracellular adhesion, fibronectin, interacting with a transmembrane receptor has proven applicable to a number of adhesion systems. There are several other extracellular glycoproteins with biological properties like fibronectin, laminin, thrombospondin, von Willebrand factor, fibrinogen/fibrin, vitronectin, and cytotactin/tenascin/hexabrachion. The structures of each of these proteins either are or very soon will be determined, opening up new possibilities for studies of function. In parallel has come the realization that the transmembrane receptor for fibronectin is only one member of the integrin family of functionally related, homologous, cell adhesion receptors. Fibronectin and related macromolecules are involved in many basic functions of cells, including cell adhesion, determination of cell shape and differentiation, cell migration, cytoskeletal organization, and organization of extracellular matrix. Thus, fibronectin and the molecules with which it interacts are important in embryogenesis, connective tissue organization, hemostasis, thrombosis, wound healing, development of immunity, hemopoiesis, malignant transformation, and tumor metastasis. The challenges to the field over the next several years are to comprehend and organize the large amount of new structural information and design experiments based upon it; learn the relative biological importance of the several seemingly redundant systems; and apply the new insights to the treatment of human diseases. The 1991 Gordon Research Conference will serve as a valuable forum to present and discuss new information, identify problem areas, and plan new approaches.

细胞外粘附纤连蛋白的范例 跨膜受体已被证明适用于许多粘附 系统。 还有其他几种细胞外糖蛋白 生物学特性，如纤连蛋白、层粘连蛋白、血小板反应蛋白、von 血友病因子、纤维蛋白原/纤维蛋白、玻连蛋白和 细胞趋化素/腱蛋白/hexabrachion。 其中每一个的结构 蛋白质要么已经被确定，要么很快就会被确定，从而开辟新的领域 功能研究的可能性。 与此同时， 认识到纤连蛋白的跨膜受体只是其中之一 功能相关的同源细胞整合素家族的成员 粘附受体。 纤连蛋白及相关大分子参与 细胞的许多基本功能，包括细胞粘附、测定 细胞形状和分化、细胞迁移、细胞骨架 组织和细胞外基质的组织。 因此， 纤连蛋白及其相互作用的分子在 胚胎发生、结缔组织组织、止血、血栓形成、 伤口愈合、免疫发展、造血、恶性 转化和肿瘤转移。 该领域面临的挑战 未来几年要理解并组织大量的 新的结构信息和基于它的设计实验；学习 几个看似多余的因素的相对生物学重要性 系统；并将新见解应用于人类疾病的治疗。 1991 年戈登研究会议将作为一个有价值的论坛 呈现和讨论新信息、识别问题领域并计划新的 接近。
