| Outline of Final Research Achievements |
We isolated the dedifferentiated fat (DFAT) by ceiling culture of mature adipocytes obtained from human buccal fat pads.DFAT expressed neuronal markers nestin, sox2. Moreover, it had properties similar to those of mesenchymal stem cells from Flow cytometric analysis. Although there was no difference in the infarct side surface area by xenografting these cells to a cerebral infarction disease model mouse, functional recovery was observed in the behavioral test. In addition, DFAT transplanted into mice was detected in cerebral infarct lesion. Therefore, the possibility that transplanted DFAT influences brain after infarction and contributes to promotion of functional recovery was considered.
This finding suggested the possibility of a new source of cell replacement therapy for the treatment of central nervous disorders.
