Adipose tissue contains some populations, adipose-derived stem cells (ADSCs) which can differentiate into adipogenic, chondrogenic, osteogenic, myogenic, and endothelial cells. Furthermore, adipose tissue can be easily obtained in large quantities through a simple liposuction. ADSCs are thought to be an alternate source of autologous adult stem cells for cell-based therapy. however, it is time-consuming and inefficient to harvest ADSCs by using a traditional collagenase-digestion method. To meet the demand of large quantities of ADSCs in the basic and applied research of regenerative medicine, we developed a rapid and efficient method for isolation and culture of primary ADSCs. The results indicated that the ADSCs obtained with our method possessed strong abilities of proliferation and colony formation in vitro, and could keep low level of cell senescence with stable population doubling during long-term culture in vitro. Furthermore, these harvested aDscs were capable to differentiate into osteogenic and adipogenic lineages in the specific induction medium. In addition, the results of flow cytometry analysis indicated that these ADSCs could positively express multiple CD markers, such as CD44, CD105, CD29, CD90, and CD13, and hardly expressed CD31, CD34, CD45, and CD106, which was homologous to the mesenchymal stem cells. Therefore, the aDscs isolated with our method are consistent with previously reported characteristics of the ADSCs. This new method that we established in this study is an efficient tool to isolate and culture the stem cells from adipose tissue.
