The results shown that:(1) Bufo raddei Strauch tadpole was capable of lens regeneration, which originated from the epithelial cells at dorsal iris margin by depigmentation.(2) Depigmentation of Bufo raddei Strauch during lens regeneration was by two methods: First, pigment granules initially dispersed all over the cytoplasm were moved towards the periphery of the cell, and then were directly taken up by the amoeboid cells. Second, pigment granules in a cell were first crowded in a mass, surrounded by a membranous structure in the cytoplasm, which were eventually discharged as a mass from the cell.

结果表明：花背蟾蜍蝌蚪(1)具有晶状体再生的能力，其晶状体的再生来源于虹膜背缘的上皮细胞；(2)虹膜背缘去色素是转分化的前提，主要有两种方式：一种也是最主要的方式是在晶状体被摘除后虹膜外侧产生巨噬细胞，巨噬细胞吞噬虹膜色素上皮细胞中的色素颗粒；另一种方式是虹膜色素上皮细胞自身释放色素颗粒；(3)电镜观察发现虹膜色素上皮细胞转分化过程中线粒体有明显变化，核糖体增多，粗面内质网增多，晶状体纤维分化过程中细胞核逐渐凝聚。
