Mesenchymal Precursor Cells (STRO-3 selected) (Mesoblast)

Mesenchymal precursor cells (MPCs) are isolated from human bone marrow aspirates by density gradient separation, over Ficoll, followed by STRO-3-based immunoselective magnetic activated cell sorting (MACS); cultures are then expanded.  STRO-3 is a monoclonal antibody, which reacts with an epitope of non-specific, human tissue alkaline phosphatase. Stro3 binds to the immunizing stromal cells, but lacks reactivity with peripheral blood-derived mononuclear cells.

Culture-expanded MPCs demonstrate increased gene expression of a range of stem cell markers, when compared to mesenchymal stem cells (MSCs), and exhibit a greater capacity to undergo osteogenic, adipogenic and chondrogenic differentiation.
