(A) MHCPim-wt CSCs cultured in growth media, fixed and immunolabeled for c-kit (green), Pim (red) and Topro (blue). (B) MHCPim-wt CSCs treated with dexamethasone containing media for 7 days, fixed and immunolabeled for c-kit (green), Pim (red) and Topro (blue) show decreased c-kit as well as Pim expression. (C) MHCAkt-nuc CSCs cultured in growth media, fixed and immunolabeled for c-kit (green), myc-tag (red) and Topro (blue). (D) MHCAkt-nuc CSCs treated with dexamethasone containing media for 7 days, fixed and immunolabeled for c-kit (green), Myc-tag (red) and Topro (blue) show decreased c-kit as well as myc-tag expression. Scale bar is 100 μm.
