The purpose of this study was to determine whether the serum condition affected the gene expression in mesenchymal stem cells (MSCs)over time. To that end, we compared gene expression in MSCs maintained in regular growth medium supplemented with fetal calf serum (FCS) for 10 passages with gene expression of MSCs cultured in the same conditions for 4 passages for 2 different donors (i.e. donor3 and donor4). Likewise, we compared gene expression in MSCs maintained in regular growth medium supplemented with autologous serum(AS) for 10 passages with gene expression of MSCs cultured in the same conditions for 4 passages for the same 2 donors (i.e. donor3 and donor4). MSCs were cultured in FCS- or AS-supplemented medium and were analyzed at passage 4 and at passage 10.

View SamplesIn order to assess whether culturing adipose-derived adult stem cells (ADASCs) affect their gene expression (see Sample Growth Condition Protocol), we wanted to identify possible genes that were differentially expressed between cultured polyclonal CD31- ADASCs and freshly isolated (uncultured) polyclonal CD31- ADASCs. To that end, RNA was isolated from cultured and uncultured ADASCs from three different donors and analyzed using the Affymetrix Microarray HG-U133A. Then, using the Affymetrix program MAS 5.0 we performed three comparisons and could identify differentially expressed transcripts common between the three donors, using the Affymetrix program DMT 3.0.

View SamplesHere we show that biotin-labelled miR-34a can be loaded to AGO2, and AGO2 immunoprecipitation can pulldown biotinylated miR-34a (Bio-miR pulldown). RNA-sequencing (RNA-seq) of the Bio-miR pulldown RNAs efficiently identified miR-34a mRNA targets, which could be verified with luciferase assays. In contrast to the approach of Bio-miR pulldown, RNA-seq of miR-34a overexpression samples had limited value in identifying direct targets of miR-34a. It seems that pulldown of 30 -Biotin-tagged miRNA can identify bona fide microRNA targets at least for miR34a. Overall design: biotin-labelled miR-34a pulldown and RNA sequencing of miR-34a overexpression samples

View SamplesMicroarrays were used to examine gene expression changes that may be present in the fallopian tube epithelium of morphologically normal BRCA1 mutation positive and negative subjects. Fallopian tube epithelia has been implicated as an early point of origin for serous carcninoma. By examining the early events present in the microenvironment of this tissue between BRCA1 mutation carriers and non-carriers, we hoped to elucidate mechanisms that may lead to the development of epithelial ovarian cancer.
