| Outline of Final Research Achievements |
We have previously described a method that allows the investigator to keep a variety of specimens wet in the high vacuum environment of the electron microscope by encasing the organisms in a thin, vacuum-proof suit, the ‘NanoSuit’. In the present study, to examine the function of pseudopod-like nano structures in wound healing, which had been detected by NanoSuit method, we analyzed the regenerative tissues in hydra. The results provide evidences that the number of nano structures changed with time in the beginning of the tissue repair, which process seemed consistent with wound closing. Histological and pharmacological studies suggest that actin filaments play an important role in the regulation of the nano structures. Furthermore, we found that such structures were detected in other animals in regenerative or growing processes. Taken together, the results suggest the possibility that these nano structures would contribute to animal development and/or regeneration.
