“ 即用型 iPSC 肝类器官 ”是以人诱导多能干细胞（iPSC, induced pluripotent stem cells）为起点细胞，基于肝脏发育进程的关键分子信号，凭借 iPSC 谱系共分化技术诱导分化形成。iLiver 具有更接近人真实肝脏的细胞谱系及结构特征，为肝脏发育机制的探索、肝病模拟、药物开发与评价等研究提供可靠的模型工具。

Characteristics
Day-25 iLivers represent uniformly sized 3D spheroids, which consists of hepatocytes (ALB+), cholangiocytes (CK7+), Kupffer cells (CD68+) and hepatic stellate cells (VIM+), as identified by immunofluorescence. Scale bar = 100 μm.
Application of iLiver organoids
Modeling NASH using day-24 iLivers manifested excessive accumulation of fibrosis (a-SMA staining), along with an increased secretion level of clinical fibrosis marker PIIINP by ELISA analysis.
