摘要： Simple Summary In this study, we aimed to improve the culture system for chicken embryonic-derived pluripotent stem cells (PSCs). These cells have immense potential in various fields, such as growth and development studies, vaccine production, and preserving genetic resources. However, establishing a stable and efficient culture system for chicken PSCs remains a challenge. We investigated the effects of different signaling pathways and feeder layers on the derivation and maintenance of chicken PSCs. Our results show that using STO cells as feeder layers, along with specific signaling pathway inhibitors, allows for the efficient derivation of chicken PSC-like cells. These cells exhibit characteristics of pluripotency and can differentiate into various cell types. This research enhances our understanding of chicken PSC culture conditions and lays the groundwork for their biomedical and biotechnological applications.Abstract The utilization of chicken embryonic-derived pluripotent stem cell (PSC) lines is crucial in various fields, including growth and development, vaccine and protein production, and germplasm resource protection. However, the research foundation for chicken PSCs is relatively weak, and there are still challenges in establishing a stable and efficient PSC culture system. Therefore, this study aims to investigate the effects of the FGF2/ERK and WNT/beta-catenin signaling pathways, as well as different feeder layers, on the derivation and maintenance of chicken embryonic-derived PSCs. The results of this study demonstrate that the use of STO cells as feeder layers, along with the addition of FGF2, IWR-1, and XAV-939 (FIX), allows for the efficient derivation of chicken PSC-like cells. Under the FIX culture conditions, chicken PSCs express key pluripotency genes, such as POUV, SOX2, and NANOG, as well as specific proteins SSEA-1, C-KIT, and SOX2, indicating their pluripotent nature. Additionally, the embryoid body experiment confirms that these PSC-like cells can differentiate into cells of three germ layers in vitro, highlighting their potential for multilineage differentiation. Furthermore, this study reveals that chicken Eyal-Giladi and Kochav stage X blastodermal cells express genes related to the primed state of PSCs, and the FIX culture system established in this research maintains the expression of these genes in vitro. These findings contribute significantly to the understanding and optimization of chicken PSC culture conditions and provide a foundation for further exploration of the biomedical research and biotechnological applications of chicken PSCs.
