Abstract
AIM: This study was performed to evaluate the effects of intravenously transplanted rat bone-marrow derived mesenchymal stem cells (rBMSCs) in an acute brain trauma model using serial 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) in rat models.



ANIMALS, METHODS: Trauma models were made using a controlled cortical impact injury device. The stem cell treatment group was treated with intravenous injections of BMSCs, and models without stem cell therapy comprised the control group. Serial 18F-FDG PET images were obtained 1, 7, 14, 21, and 28 days after trauma. The difference in 18F-FDG uptake between day 1 and each time point after trauma was analyzed with SPM2 (uncorrected p < 0.005).



RESULTS: The stem cell treatment group demonstrated significantly higher 18F-FDG uptake in the right parietal region at 14 days after trauma than at 1 day after trauma. An increase in glucose metabolism in the right parietal cortex appeared on days 21 and 28 after trauma in the group without stem cell treatment. The 18F-FDG uptake in the brain was improved over a broader area, including the right parietal and right primary somatosensory cortex, on days 21 and 28 after trauma in the stem cell treatment group compared with the group without stem cell treatment.



CONCLUSION: BMSC therapy in trauma models led to improved glucose metabolism. This result might support the therapeutic effect of stem cells in brain trauma.
