Combined miRNA and mRNA analysis of CD133(+) and CD34(+) cells

ABSTRACT: Microarray and miRNA analysis of CD133(+), CD34(+)CD133(-) and CD133(-)CD34(-) cells The goal of the experiment was the comparison of expression levels of mRNA and miRNA in CD133(+) and CD34(+)CD133(-) cells The RNA of CD133(+), CD34(+)CD133(-) and CD133(-)CD34(-) bone marrow cells was amplified by using the µMACSTM SuperAmpTM Kit (Miltenyi Biotec).

MicroRNAs (miRNAs) have been shown to play an important role in hematopoiesis. To elucidate the role of miRNAs in the early steps of hematopoiesis, we directly compared donor-matched CD133(+) cells with the more differentiated CD34(+) CD133(-) and CD34(-) CD133(-) cells from bone marrow on the miRNA and mRNA level. Using quantitative whole genome miRNA microarray and sequencing-based profiling, we found that between 109 (CD133(+) ) and 216 (CD34(-) CD133(-) ) miRNAs were expressed. Quantificatio  ...[more]
