Fig. 4From: Pharmacological EZH2 inhibition combined with retinoic acid treatment promotes differentiation and apoptosis in rhabdomyosarcoma cellsCombination treatment induces a pro-differentiation phenotype in RD spheroids and cell death in RH30 spheroids. Representative images of haematoxylin and eosin staining (H & E) and immunohistochemistry (IHC) of proteins in RD A and RH30 B spheroids after 6 days of treatment. Percentage of cells stained in immunohistochemistry (IHC) of proteins in RD and RH30 spheroids after 6 days treatment using antibodies targeting C Ki67, D H3K27me3, E Myosin Heavy Chain (MHC), F Myogenin and G Cleaved Caspase 3Back to article page
