鸡胚及禽类细胞系在生物医药领域的应用及研究进展

鸡胚因发育过程清楚，长久以来作为基础和应用科学研究领域重要的实验模型，尤其在鸡胚发育早期绒毛尿囊膜阶段，因其血管丰富，是天然的免疫缺陷宿主，是病理学、药理学和肿瘤学等研究领域的理想实验模型。作者简述了发育早期的鸡胚组织结构，并介绍了鸡胚绒毛尿囊膜在肿瘤研究、血管生成、器官移植、烧伤等疾病机理研究中的应用，以及在鸡胚病理模型基础上进行的抗肿瘤药物筛选的应用。重点介绍了鸡胚及禽类细胞系在病毒繁殖和疫苗生产、治疗性蛋白和单抗生产方面的应用研究进展。多种人源病毒、禽源病毒、支原体等可在鸡胚及禽类细胞上增殖，并用于疫苗生产。作者对常用的禽类纤维原细胞和多能干细胞的发展和特点进行了阐述，并总结了商业化的禽类细胞系来源以及部分易感病毒。鸡胚表达系统能够在目的蛋白特定位点产生人源化糖基，减少目的蛋白对人的过敏反应，且禽蛋廉价易得，可作为生产人用单克隆抗体和治疗性蛋白的合适供体。作者介绍了鸡胚及禽类细胞系在生物医药领域应用的最新进展，并对鸡胚作为动物模型在未来的应用进行了展望。

The Application and Research Progress of Chicken Embryo and Avian Cell Lines in Biomedicine

Chicken embryo has long been an important experimental model in basic and applied science because of its clear development process,especially in the early development of chicken embryo chorioallantoic membrane stage,due to its abundant blood vessels,it is a natural immunodeficiency host and can be used as an ideal experimental model for pathology,pharmacology and oncology research.The authors briefly described the tissue structure of early stage of chicken embryo,the application of chick embryo chorioallantoic membrane model in tumor,angiogenesis,organ transplantation,burn and other diseases,and the application of anti-cancer drug screening based on the pathological model of chicken embryo.The advances in the application of chicken embryo and avian cell lines in virus reproduction,vaccine production,therapeutic protein production and monoclonal antibody production were reviewed.A variety of human viruses,avian viruses and mycoplasma can proliferate in chicken embryos and avian cell lines and be used in vaccine production.In this paper,the development and characteristics of commonly used avian fibroblasts and pluripotent stem cells were described,and the source of commercial avian cell lines and some susceptible viruses were summarized.Chicken embryo expression system can produce human glycosylates at specific sites of target proteins,reduce the allergic reaction of the target protein to human,and poultry eggs are cheap and easily available,so it can be used as a suitable donor for the production of human monoclonal antibodies and therapeutic proteins.In this paper,the recent progress in the application of chicken embryos and avian cell lines in the field of biomedicine was introduced,and the future application of chicken embryos as animal models was forecasted.
