Immunofluorescence characterization. A: Spinal cord cells and human fetal neural stem cells (cultured for 3 passages with serum-containing spinal cord cell medium) were labelled with indicated antibody. Arrows show examples of stained cells. Scale bars = 10 μm. B: Western blot analysis for indicated antibodies. A main band at the expected size is observed for the three antibodies in spinal cord stem cells. SC p6, SC p7: spinal cord cells analysed at passages 6 and 7. MSC: human mesenchymal stem cells isolated from bone marrow.
