FIG. 1.

Morphology of different primary cells in culture. Representative brightfield images of cells in vitro at passage 3. (A) BM-derived MSCs, (B–D) show images from three different patient-derived cultures of CMSCLC. Brightfield image showing morphology of human CDCs (E) Brightfield image of CMSCLC CFU (F). All scale bars = 100 μm. CMSCLC cultures derived from three different patient tissue samples were assessed for their ability to form CFUs under standard MSC culture conditions, and BM was also assessed for CFU formation ability (G). The number of CFUs formed per culture at passage 1 is represented graphically. MSCs, mesenchymal stem cells; CMSCLC, cardiac-derived mesenchymal stem cell-like cells; BM, bone marrow. Color images are available online.
