Expression of SMAD5β in hematopoietic and leukemic cells.
A representative autoradiograph of multiplexed RT-PCR products resolved on a poly-A site. The upper band (307 bp) representsSMAD5β; the middle band (170 bp) represents the full-length SMAD5; and the lower band (114 bp) represents the internal control, β-2-m. Templates used for amplification are as indicated: peripheral blood mononuclear cells (PBMCs), normal bone marrow progenitor cells (CD34+), acute myelogenous leukemia (ML-3), erythroleukemia (TF1), acute myelogenous leukemia (AML193), erythroleukemia (HEL), acute myelogenous leukemia (KG1), chronic myelogenous leukemia in erythroid blast crisis (K562), and myelomonocytic leukemia (U937).
