人类胎儿肝脏类器官 (FLOs) 成功模拟肝脏发育和免疫细胞共同发育. 这种突破性的有机体系统可以研究肝损伤和潜在的再生疗法.
科学领域:
- 干细胞生物学 干细胞生物学
- 发育生物学是发展生物学.
- 免疫学 免疫学 免疫学
背景情况:
- 肝脏发育涉及肝脏和免疫细胞之间的复杂相互作用.
- 目前的体外试验模型缺乏内生的血液共同发育,限制免疫细胞的输出.
- 需要一个复制发育利基的模型来研究这些相互作用.
研究的目的:
- 开发人类胎儿肝脏类器官 (FLOs),这些器官可以容纳多能造血系统.
- 模拟肝脏发育和损伤中的复杂多系相互作用.
- 为了研究肝脏和免疫系在内源性利基内的共同发展.
主要方法:
- 从人类多能干细胞 (hPSCs) 产生FLOs.
- 血源性半皮和肝脏内皮在FLOs中的共同发展.
- 通过转录组学,免疫类型和功能测定,评估造血原生细胞和上皮细胞谱系潜力.
主要成果:
- FLOs成功地支持了肝胆,内皮,介质细胞系和多能造血原生细胞的出现.
- 造血和肝系在FLO微环境中成熟,没有外部因素.
- FLOs揭示了一种IL-8介导的中性粒细胞驱动的损伤反应在脂毒性损伤中,阐明了肝脏内在的免疫机制.
结论:
- FLOs提供了血液-肝细胞生成和肝脏先天免疫的生理相关模型.
- 这个系统回顾了胎儿肝脏的关键功能,为研究肝脏发育和免疫中介损伤提供了一个平台.
- FLOs作为调查儿科肝病和再生疗法的翻译工具.
