Outline of Final Research Achievements |
When mature adipocytes are subjected to an in vitro dedifferentiation strategy referred to as ceiling culture, these mature adipocytes can revert to a more primitive phenotype and gain cell proliferative ability. We refer to these cells as dedifferentiated fat (DFAT) cells. In the present study, we examined the multilineage differentiation potential of DFAT cells. DFAT cells obtained from adipose tissues of various animals exhibited a fibroblast-like morphology and sustained high proliferative activity. In vitro differentiation analysis revealed that DFAT cells could differentiate into adipocytes, osteoblasts and nerve cells under appropriate culture conditions. These results indicate that DFAT cells represent a type of multipotent progenitor cell. Since DFAT cells can be prepared from a small quantity of adipose tissue, they could facilitate cell-based therapies in small companion Animals such as dogs and cats.
