Figure 6From: Establishment of a new human osteosarcoma cell line, UTOS-1: cytogenetic characterization by array comparative genomic hybridizationImmunohistochemical findings. A, B. UTOS-1 cells are negative for AE1/AE3 and keratin mix. C, D, E. Most UTOS-1 cells are positive for vimentin, OP, and OC. F. Staining for ALP was performed using a modified cytochemical method. ALP activity is visible as blue staining. UTOS-1 cells are strongly positive for ALP.Back to article page
