Isolation and Characterization of Human Mesenchymal Stromal Cell Subpopulations: Comparison of Bone Marrow and Adipose Tissue

Preparations of mesenchymal stromal cells (MSCs) are generally obtained from unfractionated tissue cells, resulting in heterogeneous cell mixtures. Several markers were proposed to enrich these cells, but the majority of these markers are defined for bone marrow (BM). Moreover, the surface markers of freshly isolated MSCs also differ from those of cultured MSCs in addition to a phenotypic variation depending on the MSC source. For tissue...
