Degeneration, scar formation and regeneration have been studied after section of the optic nerve in the frog. In the normal optic nerve two types of macroglial cell were identified: astrocytes and oligodendroglia. Degeneration after injury proceeded rapidly in comparison with mammals but did not lead to the production of a dense scar. Before much scarring had developed, regenerating axons penetrated the lesioned area.
对青蛙视神经切断术后的变性、瘢痕形成和再生进行了研究。在正常的视神经中,鉴定出两种类型的大胶质细胞:星形胶质细胞和少突胶质细胞。与哺乳动物相比,损伤后的变性进展迅速,但并未导致致密瘢痕的形成。在形成大量瘢痕之前,再生轴突就穿透了损伤区域。
