Abstract

The aim of the present study was to investigate the effect of bone marrow mesenchymal stem cell (MSC) transplantation on brain‑derived neurotrophic factor (BDNF) expression in the striatum of Tourette syndrome (TS) rats. In addition, the possible mechanism of MSC transplantation in the treatment of TS was investigated. A total of 72 Wistar rats were randomly allocated into the control (sham surgery) group and the two experimental groups, including the TS+vehicle and TS+MSC. MSCs were co‑cultured with 5‑bromodeoxyuridine for 24 h for labeling prior to grafting. An autoimmune TS rat model was successfully established in the present study. Rat MSCs were cultured and expanded using density gradient centrifugation in vitro, identified by flow cytometry and then transplanted into the striata of the TS+MSC group rats. The mRNA and protein expression levels of BDNF were detected by RT‑qPCR and ELISA, respectively. The results indicated that the stereotypic behavior of TS rats was reduced 7 days after MSC transplantation, while the mRNA and protein BDNF levels in the striatum increased, compared with the sham surgery group (P<0.05). In addition, the BDNF mRNA and protein expression level was lower in the striatum of TS+MSC transplantation, compared with that in TS+vehicle rats. In conclusion, intrastriatal transplantation of MSCs may provide relief from stereotypic TS behavior, since the BDNF level was reduced in TS rats after MSC transplantation.
