| Outline of Final Research Achievements |
We compared osteogenic and adipogenic differentiation potency between MSCs isolated and cultured from normal adipose tissues and atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) from the same patients. We found greater osteogenic differentiation potency in ALT/WDL-derived MSCs than in normal fat-derived MSCs. In adipogenic differentiation, contrary to our expectations, more fatty acid droplets were observed in normal fatderived MSCs than in ALT/WDL-derived MSCs. In osteogenic differentiation, as expected, MSCs derived from ALT/WDL had higher differentiation potency than normal fat-derived MSCs. The gap of osteogenic differentiation potency based on ALP staining between ALT/WDL-derived MSCs and normal fat-derived MSCs disappeared as Nutlin-3 concentration increased, suggesting that greater osteogenic differentiation could be caused by amplied MDM2 in ALT/WDL.
