Abstract (original English)
Pluripotent embryonic stem cells (ESC) have the potential to differentiate into any cell type of the three germ layers. Differentiation processes depend on genetic and epigenetic factors. The guidance of cell fate determination by microRNAs (miRs) seems important for embryonic development and cell lineage decisions. MiRs are short, single-stranded, noncoding RNA molecules that regulate through posttranscriptional modulation, a subset of target genes involved in cell differentiation and specific cell function. We have used microarray profiling of miRs in the mouse embryonic stem cell line CGR8. Comparison of the miR profiles of undifferentiated stem cells with mesodermal progenitors cells (day 5), preadipocytes (day 10), and adipocytes (day 21) showed that the expression level of 129 miRs changed (twofold) during adipogenic differentiation. We identified 10 clusters of differentially expressed miRs, which contain putative markers and regulators of mesodermal differentiation and cell fate determination into adipocytes. Notably, the adipocyte-specific miRs 143 and 103 were upregulated from day 10 onward. We have therefore demonstrated and characterized the dynamic profile of miR expression during murine adipogenic differentiation in vitro, including the initial differentiation from ESC via mesenchymal progenitors up to adipocytes. Our findings and experimental approach provide a s
