Abstract:

BACKGROUND: Mesenchymal stem cells were first discovered in the bone marrow, and the number of studies concerning bone marrow mesenchymal stem cells is also the most. But the bone marrow mesenchymal stem cells with limited sources have the very low content. In recent years, mesenchymal stem cells have been isolated from human fetal tissue, which are similar to bone marrow mesenchymal stem cells in term of biological properties, but both of them have not been reported clearly in comparison of their adipogenic abilities.
OBJECTIVE: To compare the proliferative and adipogenic differentiation capacity of human bone marrow and fetal tissue-derive mesenchymal stem cells.
METHODS: Mesenchymal stem cells were obtained from the bone marrow by adherence culture and from fetal tissue by collagenase digestion. Cells were identified by flow cytometric assay. Proliferative potential of mesenchymal stem cells were detected by cell counting method. After adipogenic induction for 14 days, oil red O staining was used for cell counting, and adipogenic differentiation capacities of mesenchymal stem cell from two sources were measured.
RESULTS AND CONCLUSION: Mesenchymal stem cells in spindle shape were successfully harvested from both of human bone marrow and fetal tissue, which were positive for CD73, CD90 and CD105, and negative for CD14, CD34 and CD45. The proliferative capacity of fetal tissue-derived mesenchymal stem cells was stronger than that of bone marrow mesenchymal stem cells (P < 0.01). After adipogenic induction for 14 days, mesenchymal stem cells from two sources were both positive for oil red O, but the in vitro adipogenic capacity of the bone marrow mesenchymal stem cells was stronger than that of fetal tissue-mesenchymal stem cells (P < 0.01).
