Fig. 5. MRI analysis of the healing ratio of periodontal bone defects and tracking the survival of transplanted cells (A). MRI images of rats at 0, 3, 6, and 9 weeks after surgery. Red arrows indicate the low-intensity artifact signal caused by MIRB. (B) The average healing percent of bone tissue at each time point was calculated according to the results of the MRI. Healing percent=(total defect area − present defect area)/total defect area. ^%,&,*: SHED (MIRB) group is compared with SHED, Fibrin, and PBS groups, respectively. ^#,$: SHED group is compared with Fibrin and PBS groups, respectively. ^%,&,*,#,$p<0.05. ^{%%,&&,**,##,$$}p<0.01.
