Abstract

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.
