Abstract:

BACKGROUND: Adipose-derived stem cells and bone marrow mesenchymal stem cells are used widely in cartilage tissue engineering, and there are many similarities in biological characteristics between two kinds of cells.
OBJECTIVE: To compare the chondrogenic potential of bone marrow mesenchymal stem cells and adipose-derived stem cells in vitro.
METHODS: Adipose-derived stem cells were isolated from the 3-month-old New Zealand white rabbits’ abdomen. Bilateral femurs of rabbits were obtained, and then the bone marrow mesenchymal stem cells were separated with the adherence screening method. The growth curve of the passage 3 adipose-derived stem cells and bone marrow mesenchymal stem cells were drawn, and the doubling time of two kinds of cells was compared. Then the passage 3 adipose-derived stem cells and bone marrow mesenchymal stem cells were treated with chondrogenic induction. After induced for 14 days, the adipose-derived stem cells and bone marrow mesenchymal stem cells were treated with toluidine blue staining and type Ⅱ immunohistochemistry staining respectively. 
RESULTS AND CONCLUSION: Primary bone marrow mesenchymal stem cells showed aggregative growth, while the primary adipose-derived stem cells were in single and scattered growth. The proliferation speed of adipose-derived stem cells was faster than that of bone marrow mesenchymal stem cells, while the doubling time of adipose-derived stem cells was shorter than that of the bone marrow mesenchymal stem cells. After chondrogenic induction for 14 days, both adipose-derived stem cells and bone marrow mesenchymal stem cells could express glycosaminoglycans and type Ⅱ collagen, and the expression level of type Ⅱ collagen in bone marrow mesenchymal stem cells after chondrogenic induction was higher than that in the adipose-derived stem cells. The in vitro proliferation of adipose-derived stem cells and bone marrow mesenchymal stem cells was rapid and stable, but the proliferative ability of adipose-derived stem cells was faster than that of bone marrow mesenchymal stem cells. When cultured in single layer, both adipose-derived stem cells and bone marrow mesenchymal stem cells could transform into chondrocytes under certain conditions, but bone marrow mesenchymal stem cells seemed to be more potential than adipose-derived stem cells.
