目的　研究HERG在CD1小鼠膽囊組織及膽囊Cajal間質細胞（interstitial cells of Cajal,ICC）中的表達及其意義。
方法　采用免疫組化方法及Western blot法檢測CD1小鼠膽囊組織中HERG蛋白的表達； RT-PCR法檢測膽囊組織中HERG mRNA的表達；雙重免疫熒光標記法檢測急性分離膽囊ICC中HERG蛋白的表達。
結果　免疫組化結果顯示，HERG在CD1小鼠膽囊組織的細胞漿中呈黃色或棕黃色陽性反應，主要表達于膽囊黏膜層； RT-PCR法檢測結果顯示，CD1小鼠膽囊組織中HERG mRNA陽性表達； Western blot檢測結果顯示，CD1小鼠膽囊組織中HERG蛋白陽性表達；雙重免疫熒光標記法檢測結果顯示，CD1小鼠膽囊ICC 中 HERG蛋白陽性表達。
結論　CD1小鼠膽囊組織以及膽囊ICC中均存在HERG的表達，HERG可能與ICC起搏功能有關。
