Identity, proliferation capacity, genomic stability and novel senescence markers of mesenchymal stem cells isolated from low volume of human bone marrow (III)

ABSTRACT: Human bone marrow mesenchymal stem cells (hBM-MSCs) hold promise for treating diseases for which currently no therapeutic options exist. High quantities of MSCs are needed, requiring extensive cell expansion in long-term culture. However, the fundamental biological properties of MSCs can be altered by culture conditions. In this study, hBM-MSCs were isolated from residual human bone marrow (hBM) material and expanded to clinically relevant numbers at passage 3-4. The cells had normal morphology, proliferation rate, immunophenotype and karyotype. Despite the chromosomal stability, after additional three passages (P6-P7) hBM-MSCs entered senescence state, confirmed by SA-β-galactosidase staining and paralleling the slower proliferation, altered morphology and imunophenotype. qRT-PCR array p
