Undifferentiated plastic-adherent cells derived from murine bone marrow (BM; A), perirenal adipose tissue (PAT; B), and mediastinal stromal tissue (MST; C) show a spindle-shaped morphology. Comparison of proliferation of murine mesenchymal progenitor cells in passage 4 and 15 (D). Mean values ± SEM derived from independent samples per experimental group (n = 3) are shown. DIC = differential interference contrast. Bar = 100 μm.
