Abstract

OBJECTIVE
There have been recent reports that mesenchymal stromal cells that are harvested from adipose tissue are able to differentiate into neurons. In the present study, we administered adipose tissue derived stem cells in rats with cerebral infarction in order to determine whether those stem cells could enhance the recovery of motor function.
METHODS
Cerebral infarction was induced by intraluminal occlusion of middle cerebral artery in rats. The adipose tissue-derived mesenchymal stem cells were harvested from inguinal fat pad and proliferated for 2 weeks in DMEM media. Approximately 1 x 10(6) cells were injected intravenously or into subdural space of the peri-lesional area. The rotor rod test was performed at preoperative state(before MCA occlusion), and 1, 2, 3, 4, 6, 8 and 10 weeks after the cell therapy.
RESULTS
The motor functions that were assessed by rotor rod test at 1 week of the cell therapy were nearly zero among the experimental groups. However, there was apparent motor function recovery after 2 weeks and 4 weeks of cell injection in intravenously treated rats and peri-lesionaly treated rats, respectively, while there was no significant improvement till 8 weeks in vehicle treated rats.
CONCLUSION
These results demonstrate that the adipose derived stem cell treatment improves motor function recovery in rats with cerebral infarction.
