CTAs in cancer cell lines derived from tissues of neuroectodermal and mesodermal origin. (a) Cell morphology of neuroblastomas and glioblastomas and immunostaining of these cell lines by antibody against OCT4. Scale bar = 100 μm. (b) Immunocytochemical analysis of OCT4 expression in rhabdomyosarcoma and osteosarcoma cell lines. Scale bar equal 100 μm. (c) CTA expression profiles of cancer cell lines of neuroectodermal and mesodermal lineages.
