Abstract (original English)
Somatic stem cells can be isolated from a variety of sources. Although some studies have suggested that somatic stem cells may represent a cell population that is very similar to embryonic stem (ES) cells, it remains unclear whether somatic stem cells retain the potential to differentiate into any cell type derived from the three germ layers. In this study, we investigated the transdifferentiation potential of somatic stem cells using adipose tissue-derived stem/progenitor cells (ASCs; mesodermal stem cells) and pancreatic stem cells (endodermal stem cells). Previous reports from other groups describe the protocol that has been used to differentiate ASCs or mesenchymal stem cells (MSCs) in bone marrow into insulin-producing cells. Induction 1: ASCs were cultured for 3 days in ultra-low attachment plates under serum-free conditions. Induction 2: ASCs were cultured for 24 h with L-DMEM, and reinduced with serum-free H-DMEM for another 10 h. Unlike previous reports, we did not get ASCs to express any pancreas-specific genes, including insulin-1 or insulin-2. Pancreatic stem cells were induced to differentiate into adipo/osteogenic by the following protocols. Induction protocol 1: ACSs were cultured for 7 days with medium containing indometacin, dexamethasone, hydrocortisone, and insulin for adipogenic differentiation. Induction protocol 2: The cells were cultured for 7 days with m
