Abstract (original English)

Regenerative therapeutic approaches involving the transplantation of stem cells differentiated into insulin-producing cells are being studied in patients with rapidly progressing severe diabetes. Adipose-derived mesenchymal stem cells have been reported to have varied cellular characteristics depending on the biological environment of the location from which they were harvested. However, the characteristics of mesenchymal stem cells in type II diabetes have not been clarified. In this study, we observed the organelles of mesenchymal stem cells from patients with type II diabetes under a transmission electron microscope to determine the structure of stem cells in type II diabetes. Transmission electron microscopic observation of mesenchymal stem cells from healthy volunteers (N-ADSC) and those from patients with type II diabetes (T2DM-ADSC) revealed enlarged nuclei and degenerated mitochondrial cristae in T2DM-ADSCs. Moreover, T2DM-ADSCs were shown to exhibit a lower expression of Emerin, a constituent protein of the nuclear membrane, and a decreased level of mitochondrial enzyme activity. In this study, we successfully demonstrated the altered structure of nuclear membrane and the decreased mitochondrial enzyme activity in adipose-derived mesenchymal cells from patients with type II diabetes. These findings have contributed to the understanding of type II diabetes-associated ch
