Abstract:

BACKGROUND: Bone marrow mesenchymal stem cells are rare in vivo. It is important to purify, proliferate and differentiate bone marrow mesenchymal stem cells in vitro for further research.
OBJECTIVE: To evaluate the biological characteristics, phenotype and multiple differentiation potential cultivation of bone marrow mesenchymal stem cells that are isolated, cultured and purified using the whole bone marrow adherence method.
METHODS: Bone marrow mesenchymal stem cells were isolated, purified and cultured by the whole bone marrow adherence method. Morphological observation and flow cytometry determination of cell surface markers were performed. Osteogenic and adipogenic differentiation of bone marrow mesenchymal stem cells was induced.
RESULTS AND CONCLUSION: We successfully purified and proliferated bone marrow mesenchymal stem cells with high cell viability and differentiation ability. Fibroblast-like cells were harvested, expressing CD29 and CD90, but not CD45. Following osteogenic and adipogenic induction, cells were positive for oil red O staining and alizarin red staining. The whole bone marrow adherence method is easy to operate, has little impact on cell viability, and can be used to harvest high-purification bone marrow mesenchymal stem cells with high cell viability and differentiation ability.
