Outline of Final Research Achievements

This research was performed to establish the principle of the treatment for the wound by using cells called macrophage. Mice in which the state of macrophage can be detected by fluorescence were generated. Skin defects were made on the back of the mice, and the process of the wound healing was observed by microscopy. Methods to increase the macrophages, which can promote the wound healing, from the blood, and the potency of the macrophages were examined. In addition, the role of macrophages during the cartilage regeneration in the body was examined using several methods including electron microscopy by which minute structures can be observed. As a result, it was strongly suggested that macrophages affect chondrocytes directly in the early phase of the cartilage regeneration.
