目的 探討卵圓細胞在進行性肝損傷過程中的分布及遷移規律。
方法 清潔型SD 大鼠60只隨機分為對照組（20只）和實驗組（40只），兩組均于肝癌造模后的不同時相切取肝組織標本進行形態學觀察、常規病理和原癌基因編碼蛋白（C-kit）免疫組化檢測。
結果 對照組大鼠肝臟表面光滑，組織學形態正常，偶見C-kit陽性細胞。實驗組于肝癌造模后的第2周，首先于匯管區發現卵圓細胞沿膽管上皮依次排列增生，這些卵圓細胞呈C-kit陽性表達。隨著肝損傷進行性加重，卵圓細胞以匯管區為中心向肝小葉穿插、遷移。肝癌形成期，以混合型癌多見，癌結節內外均見有卵圓細胞，此期C-kit陽性細胞仍集中于匯管區。
結論 卵圓細胞為肝組織內對損傷反應最敏感的一種細胞； 肝卵圓細胞的無序遷移參與假小葉形成； 卵圓細胞與肝癌的發生密切相關。
