| Outline of Final Research Achievements |
It has been reported that the mononuclear cells which locate in the interstitial space of damaged muscle might take part in muscle fibers repair. However, the strain of these cells are not clear. In this study, trauma loaded rat skeletal muscles were observed with FIB/SEM, which were reconstructed into 3D images by the program to develop the localization and formation of stromal cells. As a result, we observed that many cells invaded it in muscle fibers, and three kinds of stromal cells were identified in the interstitial space of the gastrocnemius muscles at the 1st and the 2nd day after muscle damage. These 3 types of cells were contacted one another and formed network. At the 5th days after, stromal cells were surrounded the regenerate muscle fiber.It was suggested that these stromal cells may exchange some information which plays some important roles in regeneration process after muscle damage.
