Hematopoietic progenitor abnormalities in Ts65Dn(17¹⁶) bone marrow by semi-solid agar clonogenic colony assays.

Numbers of colonies from 25,000 unfractionated bone marrow cells cultured in granulocyte colony-stimulating factor (G-CSF, 103U/mL), granulocyte-macrophage colony-stimulating factor (GM-CSF, 103U/mL), interleukin-3 (IL3, 10ng/mL), stem-cell factor (SCF, 100 ng/mL), erythropoietin (EPO, 2U/mL), as indicated, with the type and number of colonies scored after 7 days. The number of biological replicates per genotype is given. Mean and standard deviation shown. * = P < 0.05 for comparison with Erg+/+; § = P < 0.05 for comparison with Ts65Dn/Erg+/+/Mld2 mice by unprotected Fisher’s Least Significant Difference. χ2 for difference for a given genotype compared to diploid control Erg+/+ comparing all colony numbers using rounded means shown. Blast, blast colony; G, granulocyte; GM, granulocyte-macrophage; M, macrophage; Eo, eosinophil; Meg, megakaryocyte colony.
