Outline of Final Research Achievements |
Human iPS and ES cells have adipogenic potentials in vitro. Matrigel containing adipocyte-like cells derived from human iPS and ES cells was transplanted into the subcutaneous tissue of nude mice for 1-4 weeks. Histological analyses and gene expression analyses revealed the presence of adipocyte-like cells at 1-4 weeks. These cells can survive and maintain the differentiated properties of the adipocytes for at least 4 weeks after the transplantation. Then, iPS cells were generated from 5 patients with congenital generalized lipodystrophy, 2 patients with acquired generalized lipodystrophy and a patient with familial partial lipodystrophy. Among them, iPS cells from lipodystrophic patients with BSCL2 nonsense mutations (BSCL2-iPS cells) exhibited marked reduction of lipid droplet formation after adipogenic differentiation, compared with those from healthy subjects. BSCL2-iPS cells could provide valuable models with which to study the pathophysiology of lipodystrophy.
