We attempted to establish the human ES cells harboringHCN4-GFP BAC vector to isolate human pluripotent stem cell-derived pace-making cells using physiological approach. We construct BAC vector harboring the knocked GFP gene into the promoter region of HCN4 gene and introduced it into human ES cells (KhES-1) to establish the several clones including clone #1. These clones expressed the pluripotent gene markers and normal karyo type of chromosome. The embryoid body derived from clone#1 to differentiate cardiac cells included the HCN4-GFP positive cells at 5% out of total human ES cells. HCN4-GFP positive cells expressed cardiac contractile proteins and HCN4 channels. HCN4-GFP positive cells expressed the several ion channels being responsible for their automaticity. The Ca transient derived from the aggregation of HCN4-GFP positive cells propagated into the HL-1 atrial cell-sheet. Taken together, we establish the human ES cells harboringHCN4-GFP BAC vector and successfully isolate the HCN4-GFP positive pacemakingcells.

我们试图利用生理学方法建立携带hcn4 - gfp BAC载体的人胚胎干细胞，以分离人多能干细胞衍生的起搏细胞。我们在HCN4基因启动子区构建含有敲除GFP基因的BAC载体，并将其导入人ES细胞（KhES-1），建立了包括克隆1在内的多个克隆。这些克隆表达了多能性基因标记和正常核型染色体。从克隆1中获得的胚胎样体分化心脏细胞包括HCN4-GFP阳性细胞，占人类胚胎干细胞总数的5%。HCN4- gfp阳性细胞表达心脏收缩蛋白和HCN4通道。HCN4-GFP阳性细胞表达了负责其自动性的几个离子通道。由HCN4-GFP阳性细胞聚集产生的Ca瞬态传播到HL-1心房细胞片。综上所述，我们建立了携带HCN4-GFP BAC载体的人ES细胞，并成功分离出HCN4-GFP阳性起搏细胞。
