Abstract:

BACKGROUND: Rabbit bone marrow mesenchymal stem cells as a kind of adult stem cells with strong proliferation and multilineage differentiation potential exhibit a tremendous application potential in tissue engineering and biological therapy.
OBJECTIVE: To in vitro culture, proliferate and identify rabbit bone marrow mesenchymal stem cells and to observe cell biological characteristics.
MEHTODS: Bone marrow of rabbits was extracted under sterile conditions to separate bone marrow mesenchymal stem cells using the whole bone marrow adherence method and Percoll density gradient centrifugation method. Afterwards, the cells were purified and proliferated using differential adherence method. Morphology and growth pattern of cells were observed under microscope, and expression of cell surface antigen markers was detected by flow cytometry.
RESULTS AND CONCLUSION: Rabbit bone marrow mesenchymal stem cells presented with short adherent time and fast growth. After passage and purification, impurities cell counts were decreased. Primary cells presented with triangular, fusiform and spindly shapes. Passage 5 cells with single shape showed the typical polar swirling growth, and could not express CD34 and CD45, but expressed CD29 and CD44. These findings indicate that the cells cultured using the whole bone marrow adherence method and Percoll density gradient 
centrifugation method possess stem cell characteristics in morphology, surface markers and multilineage differentiation, which have been identified as bone marrow mesenchymal stem cells by flow cytometry.
