The amputations of the hydra in the hypostomal region have been performed. The material has been fixed in various time intervals after the amputation (from 5 min to 19 hours).The healing of the wound is done with the participation of all endodermal cells, the regeneration process with the help of zymogenic cells which dedifferenciate into neoblasts, and the neoblasts develop into ectodermal cell elements by differentiation. The old ectoderm does not take part in forming the young ectoderm in the wound area.The participation of endoderm in healing the wound and in the regeneration has been stated by the method for the acid phosphatase. It is supposed that the zymogenic cells also in normal hydra supply the ectoderm with new cells.
已在水螅口盘区进行了截肢手术。截肢后在不同时间间隔(从5分钟到19小时)对材料进行了固定。伤口愈合是在所有内胚层细胞的参与下完成的,再生过程借助于酶原细胞,酶原细胞去分化形成成新细胞,而成新细胞通过分化发育成外胚层细胞成分。旧的外胚层不参与伤口区域新外胚层的形成。通过酸性磷酸酶方法已证实内胚层参与伤口愈合和再生。据推测,正常水螅中的酶原细胞也为外胚层提供新细胞。
