This effect was most pronounced for CD3+CD8+ T cells with an average of 0.33 CD3+CD8+ T cells (range 0–1.80) within a 10 μm radius around CD34+ blasts in sAML and an average of 0.08 CD3+CD8+ T cells (range 0–1.01) in MDS samples (p = 0.001). This evidence concerns the gene CD34 and myelodysplastic syndrome.
