摘要
目的 :比较小鸡基底乳头和豚鼠耳蜗毛细胞 β-肌动蛋白 (β- actin)分布的特点。方法 :应用免疫组织化学方法观察小鸡和豚鼠耳蜗中β- actin免疫反应活性。结果 :鸡基底乳头高、矮毛细胞的静纤毛 ,盖膜根部附着处缘上皮细胞胞浆 ,豚鼠耳蜗三排外毛细胞胞浆 ,内、外支柱细胞胞浆和指状突β- actin免疫反应阳性。结论 :小鸡和豚鼠耳蜗毛细胞具有相同结构蛋白β- actin,但两种动物之间存在明显的分布差异。
Objective:To study the distribution of β actin in the chicken and guinea pig cochlea hair cells.Method:β actin immunoreactivity was observed by immunohistochemistry.Result:β actin was located in stereocilia of hair cells and cytoplasm of marginal epithelium cells which tectorial membrane attached in basilar papilla;In the corti′s organ β actin was present in three row outer hair cells cytoplasm and the phalangeal process and cytoplasm of the tunnel cells.Conclusion:There is a common cytoskeletal protein β actin in the chick and guinea pig cochleae,but the distribution of β actin in two species are different significantly.
