Abstract

Future cell-based therapies such as tissue engineering will benefit from a source of autogenous pluripotent stem cells. There are embryonic stem cells (ESC) and autologous adult stem cells, two general types of stem cells potentilally useful for these applications. But practical use of ESC is limited due to potential problems of cell regulation and ethical considerations. To get bone marrow stem cells is relatively burden to patients because of pain, anesthesia requirement. The ideal stem cells are required of such as the following advantages: easy to obtain, minimal patient discomfort and a capability of yielding enough cell numbers. Adipose autologus tissue taken from intraoral fatty pad or abdomen may represent such a source. Our study designed to demonstrate the ability of human adipose tissue-derived stromal cells (hATSC) from human abdominal adipose tissue diffentiating into osteocyte and adipocyte under culture in vitro conditions. As a result of experiment, we identified stromal cell derived adipose tissue has the multilineage potentiality under appropriate culture conditions. And the adipose stromal cells expressed several mesenchymal stem cell related antigen (CD29, CD44) reactions. Secondary, we compared the culture results of a group of hATSC stimulated with TGF-beta1, bFGF with a hATSC group without growth factors to confirm whether cytokines have a important role of the proliferation in osteogenic differentiation. The role of cytokines such as TGF-beta1, bFGF increased hATSC's osteogenic differentiation especially when TGF-beta1 and bFGF were used together. These results suggest that adipose stromal cells with growth factors could be efficiently available for cell-based bone regeneration.
