Abstract:
Objective To analyze the differences in biological functions between bone marrow(BM)-derived CD106 mesenchymal stem cells(MSCs)and the CD106 subgroup. Methods The MSCs from normal BM were isolated and expanded.The subgroups of CD106 and CD106 MSCs were sorted.The cell proliferation and adhesion functions,chemotactic activities,adipogenic and osteogenic potentials,senescence,and senescence protein 21(p21)were detected.The capacity of translocation into nucleus of nuclear factor-kappa B(NF-κB)when stimulated by tumor necrosis factor(TNF-α)was measured. Results The proliferative ability was higher in CD106 MSCs than that in CD106 MSCs.In 48 hours,the value of optical density(OD)was significantly higher in CD106 MSCs than that in CD106 subgroup(1.004±0.028 0.659±0.023,=3.946,=0.0225).In 72 hours,this phenomenon was even more pronounced(2.574±0.089 1.590±0.074,=11.240,=0.0000).The adhesive capacity of CD106 MSCs was significantly stronger than that of CD106 subgroup(0.648±0.018 0.418±0.023,=7.869,=0.0002).Besides,the metastasis ability of CD106 MSCs were significantly stronger than that of CD106 subgroup(114.500±4.481 71.000±4.435,=6.900,=0.0005).The CD106 MSCs had signifcnatly lower proportions of senescent cells.The expression of aging protein p21 in CD106 MSCs was significantly lower than that in CD106 MSCs [(17.560±1.421)% (45.800±2.569)%,=9.618,=0.0000].Furthermore,there were no visible pigmenting cells after β-galactosidase staining in CD106 MSCs subgroup.However,in CD106 MSCs,some colored green cells were detected.The rate of NF-κB translocation into nucleus after stimulated by TNF-α was significantly higher in CD106 MSCs than CD106 MSCs [(37.780±3.268)% (7.30±1.25)%,=8.713,=0.0001]. Conclusion Bone marrow-derived CD106 MSCs possess more powerful biological functions than CD106 MSCs.
