Mesenchymal progenitor cells derived from murine bone marrow (BM), perirenal adipose tissue (PAT), and mediastinal stromal tissue (MST) show adipogenic (A; Sudan III staining) and osteogenic (B; alkaline phosphatase staining) differentiation. Cells were cultivated via monolayer (A1-3 and B1-3) or adherent "mesenchymal microsphere" (MMS outgrowths; A4-6 and B4-6). Representative areas are shown. Bar = 100 μm.
