[Differentiation potential and application of stem cells from adipose tissue].

OBJECTIVE
To introduce types and differentiation potentials of stem cells from adipose tissue, and its applications on regenerative medicine and advantages.


METHODS
The literature of original experimental study and clinical research about bone marrow mesenchymal stem cells (BMSCs), adipose-derived stem cells (ADSCs), and dedifferentiated fat (DFAT) cells was extensively reviewed and analyzed.


RESULTS
ADSCs can be isolated from stromal vascular fraction. As ADSCs have multi-lineage potentials, such as adipogenesis, osteogenesis, chondrogenesis, angiogenesis, myogenesis, and neurogenesis, they have already been successfully used in regenerative medicine areas. Dramatically, mature fat cells can be dedifferentiated and changed into fibroblast-like cells, named DFAT cells, via ceiling culture method. DFAT cells also had the same multi-lineage potentials as ADSCs, differentiating into adipocytes, osteocytes, chondrocytes, endothelial cells, muscle cells, and nerve cells. Compared with BMSCs which are commonly used as adult stem cells, ADSCs and DFAT cells have extensive sources and can be easily acquired. While compared with ADSCs, DFAT cells have good homogeneity and strong proliferation capacity.


CONCLUSION
As a potential source of stem cells, adipose tissue will provide a new promising for regenerative medicine.
