View SamplesOne of strategies to regenerate cartilage defect is transplantation of mesenchymal stem cells (MSCs). Improvements of therapeutic potential of MSCs are needed to achieve successful cartilage regeneration by transplantation of a limited number of cells. Aggregated culture is a popular method in ES and iPS cells to maintain or enhance their potentials. Here we investigated gene expression profile of aggregated MSCs. 621 genes were up-regulated and 409 genes were down-regulated more than 5-fold in MSC-aggregates compared with the number in MSCs in a monolayer culture. The most up-regulated gene was BMP2, which is one of the genes involved in chondrogenesis. Anti-inflammatory genes were also up-regulated in MSC-aggregates. The microarray data for selected genes were confirmed by real-time PCR.

View SamplesIn murine large intestinal lamina propria, CX3CR1high resident Mfs possess anti-inflammatory properties and thereby support intestinal homeostasis. Unlike other tissue-resident Ms, transcription factors that regulate differentiation and function of CX3CR1high Ms in the large intestine are poorly understood. Thus, to identify transcription factors specifically expressed in CX3CR1high Ms among large intestinal lamina propria innate myeloid cells, we comprehensively analyzed the genes expression profiles in CX3CR1high Ms, CX3CR1- CD11b+ CD11c+ cells, CD11b- CD11chigh DCs, and CD11b+CD11c- cells.

View SamplesTo determine the functions of Spi-C in innate immune responses, we investigated the overall gene expression patterns in M-CSF-BMDMFs prepared from Spicflox/flox and Lyz2-cre; Spicflox/flox mice. M-CSF-BMDMFs were stimulated with or without LPS following heme treatment and used for RNA-seq analysis. Overall design: Control and Spic–/– BMDMF pretreated with 40 µM hemin for 18 h were stimulated with (designated 'CNT_4' and 'cKO_4', respectively) or without (designated 'CNT_0' and 'cKO_0', respectively) 100 ng/ml LPS for 4 h.

View SamplesRoom temperature whole blood mRNA stabilization procedures, such as the PAX gene system, are critical for the application of transcriptional analysis to population-based clinical studies. Global transcriptome analysis of whole blood RNA using microarrays has proven to be challenging due to the high abundance of globin transcripts that constitute 70% of whole blood mRNA in the blood. This is a particular problem in patients with sickle-cell disease, secondary to the high abundance of globin-expressing nucleated red blood cells and reticulocytes in the circulation . In order to more accurately measure the steady state whole blood transcriptome in sickle-cell patients, we evaluated the efficacy of reducing globin transcripts in PAXgene stabilized RNA samples for genome-wide transcriptome analyses using oligonucleotide arrays. We demonstrate here by both microarrays and Q-PCR that the globin mRNA depletion method resulted in 55-65 fold reduction in globin transcripts in whole blood collected from healthy volunteers and sickle-cell disease patients. This led to an improvement in microarray data quality with increased detection rate of expressed genes and improved overlap with the expression signatures of isolated peripheral blood mononuclear (PBMC) preparations. The differentially modulated genes from the globin depleted samples had a higher correlation coefficient to the 112 genes identified to be significantly altered in our previous study on sickle-cell disease using PBMC preparations. Additionally, the analysis of differences between the whole blood transcriptome and PBMC transcriptome reveals important erythrocyte genes that participate in sickle-cell pathogenesis and compensation. The combination of globin mRNA reduction after whole-blood RNA stabilization represents a robust clinical research methodology for the discovery of biomarkers for hematologic diseases and in multicenter clinical trials investigating a wide range of nonhematologic disorders where fractionation of cell types is impracticable.

Overall design: Focusing on the cardiac system, we performed Reprogram-Seq on P0 mouse heart cells to generate a reference transcriptomic map. Based on the reference map, we selected TF candidates and tests 1000s of TF cocktails for direct lineage conversion by scRNA-Seq.
