Reduced Tumor Marker Expression in Reprogrammed Melanoma Cells
(A) Histological staining for the melanoma marker S100B in melanomas derived from HT-144, Mewo, and SKMEL147 cells and their respective reprogrammed progeny.
(B) In contrast to melanomas, S100B expression is restricted to neuronal-like cells in HT-144-iPCC-derived teratomas (indicated by arrows).
(C) Histological staining for epithelial cytokeratins (PanCK) in HT-144-iPCC-derived tumors and melanomas derived from the parental HT-144 cells.
(D) Histological analysis of the expression of the proliferation marker KI67 in melanomas derived from HT-144, Mewo, and SKMEL147 cells and their respective reprogrammed progeny.
