Expression of smooth muscle markers and Nkx6.1 in spinal cord cells. A-F: Immunofluorescence staining of spinal cord cells (A-E) and human mesenchymal stem cells (F). The vast majority of cells (>80%) express Nestin, Acta2, Caldesmon, Calponin and NG2. Nuclear Nkx6.1 staining is detected in Caldesmon+, Calponin+, NG2+ spinal cord cells (C, D, E) but not in human mesenchymal stem cells (F). Scale bars = 10 μm.
