BackgroundBone marrow mesenchymal stromal cells (BM-MSCs) are an essential cell type in the hematopoietic microenvironment. The question of whether MSCs from patients with different leukemias have cytogenetic abnormalities is controversial. In this study, we attempted to review the cytogenetic profiles of MSCs in patients with leukemia, and verify whether these profiles were related to different ex vivo culture conditions or to chronic or acute disease states. This information could be useful in clarifying the origin of MSCs and developing clinical applications for this cell type.MethodsA systematic literature search was performed using the PubMed search engine. Studies published over the past 15 years, i.e., between 1995 and January 2015, were considered for review. The following keywords were used: “cytogenetic,” “leukemia,” “bone marrow,” and “mesenchymal stromal cells.”ResultsSome studies demonstrated that BM-MSCs are cytogenetically normal, whereas others provided evidence of aberrations in these cellsConclusionsStudying cytogenetic changes of MSCs in a variety of leukemias will help researchers understand the nature of these tumors and ensure the safety of human stem cells in clinical applications. |
