Chicken embryonic stem cells (cESCs) isolated from the egg at the stage X hold great promise for cell therapy, tissue engineering, pharmaceutical, and biotechnological applications. They are considered to be pluripotent cells with the capacity to self-renewal and differentiate into specialized cells. However, long-term maintenance of cESCs cannot be realized now, which impedes the establishment of cESC line and limits their applications. Therefore, the separation locations, isolation methods, and culture conditions especially the supplements and action mechanisms of cytokines, including leukemia inhibitory factor, fibroblast growth factor, transforming growth factor beta, bone morphogenic protein, and activin for cESCs , have been reviewed here. These defined strategies will contribute to identify the key mechanism on the self-renewal of cESCs, facilitate to optimize system that supports the derivation and longtime maintenance of cESCs, establish the cESC line, and develop the biobank of genetic resources in chicken.
鸡胚胎干细胞(cESCs)在 X 期从鸡蛋中分离出来,在细胞治疗、组织工程、制药和生物技术应用方面具有广阔的应用前景。它们被认为是具有自我更新和分化为特定细胞能力的多能细胞。然而,目前还无法实现 cESCs 的长期维持,这阻碍了 cESC 系的建立,并限制了它们的应用。因此,本文综述了 cESCs 的分离部位、分离方法和培养条件,特别是细胞因子(包括白血病抑制因子、成纤维细胞生长因子、转化生长因子β、骨形态发生蛋白和激活素)的补充和作用机制。这些明确的策略将有助于确定 cESCs 自我更新的关键机制,促进优化支持 cESCs 的衍生和长期维持的系统,建立 cESC 系,并开发鸡的遗传资源生物库。
