CD34 and myelodysplastic syndrome: In line with these observations, we have also recently found increased numbers of early CD34+/CyMPO+ neutrophil and CD34+/CD36+/CD123lo erythroid precursors within the BM CD34+ HPC from early/low-risk MDS, while in advanced/high-risk MDS neutrophil and erythroid differentiation of CD34+ cells typically appeared to be blocked [37].
