Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The cumulus cells niche that surrounds the oocyte is essential for its maturation and presumably for the oocyte to acquire its competence to confer pluripotency. The cells cultured from the human oocyte cumulus niche (hCC) could be used as feeders for the propagation of human pluripotent stem cells in vitro.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We have previously shown that Heparin (Hep) significantly inhibited Enterovirus 71 (EV71) infection and binding in both Vero and a human neural cell line, SK-N-SH, in vitro. Therefore, in this study we intended to gain insight into the cellular and molecular mechanisms of action of Hep against clinical EV71 infection in neural cells. Instead of stating a long list of gene functions and pathways, we tried to select for EV71-induced genes that were exclusively affected by antiviral activity of Hep through a multi-level comparison and characterization.

Affymetrix Human Gene 2.0 ST Array (hugene20st), Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Stem cell-derived tissues have wide potential for modelling developmental and pathological processes as well as cell-based therapy. However, it has proven difficult to generate several key cell types in vitro, including skeletal muscle. In vertebrates, skeletal muscles derive during embryogenesis from the presomitic mesoderm (PSM). Using PSM development as a guide to establish conditions for the differentiation of monolayer cultures of embryonic stem (ES) cells into PSM-like cells without the introduction of transgenes or cell sorting.

- Affymetrix Murine Genome U74A Version 2 Array (mgu74av2), Affymetrix Mouse Expression 430A Array (moe430a)
Description
A microarray time series was generated to identify cyclic genes of the segmentation clock in the mouse. The right posterior half presomitic mesoderms (PSM) from 17 mouse embryos were dissected while the contralateral side of the embryo containing the left PSM was immediately fixed to be analyzed by in situ hybridization using a Lfng probe to order the samples along the segmentation clock oscillation cycle. Probes were produced from RNA extracted from the 17 dissected posterior half PSMs using a two-step amplification protocol and were hybridized to Affymetrix GeneChip MOE430A. The reproducibility of the amplification procedure was initially assessed by comparing array data generated from the right and the left posterior PSM from the same embryo. Because of the symmetry of the paraxial mesoderm along the left-right axis, left and right samples are expected to show overtly similar gene expression. RNA was amplified from three such sample pairs (1, a and b; 2, a and b; 3, a and b) and hybridized on Murine Genome U74Av2 array (MG-U74Av2)

Description
Purpose: Transcriptome is the entire repertoire of all transcripts present in a cell at any particular time. We undertook next-generation whole transcriptome sequencing approach to gain insight of the transcriptional landscape of the developing mouse lens. Methods: We ascertained mice lenses at six developmental time points including two embryonic (E15 and E18) and four postnatal stages (P0, P3, P6, and P9). The ocular tissue at each time point was maintained as two distinct pools serving as biological replicates for each developmental stage. The mRNA and small RNA libraries were paired-end sequenced on Illumina HiSeq 2000 and subsequently analyzed using bioinformatics tools. Results: Mapping of mRNA and small RNA libraries generated 187.56 and 154.22 million paired-end reads, respectively. We detected a total of 14,465 genes in the mouse ocular lens. Of these, 46 genes exhibited 40-fold differential expression compared to transcriptional levels at E15. Likewise, small RNA profiling identified 379 microRNAs (miRNAs) expressed in mouse lens. Of these, 49 miRNAs manifested an 8-fold or higher differential expression when compared, as above to the microRNA expression at E15. Conclusion: We report the first comprehensive profile of developing murine lens transcriptome including both mRNA and miRNA through next-generation RNA sequencing. A complete repository of the lens transcriptome of six developmental time points will be monumental in elucidating processes essential for development of the ocular lens and maintenance its transparency. Overall design: Whole transcrtiome and microRNA profilling of mouse lens using 2 embryonic (E15 and E18) and 4 postnatal stages (P0, P3, P6 and P9) in duplicates through high-throughput sequening using Illumina HiSeq2000.

Description
Purpose: In this study, we identify global transcriptome alterations following removal of individual or multiple miR-196 family members in mouse. Next generation sequencing-derived transcriptome profiling (RNA-seq) was performed. Methods: A GFP reporter cassette was engineered to replace the mature miR-196a1 and miR-196a2 miRNA genomic loci in mouse (creating a knockout). GFP positive cells from an extensive knock-out allellic series of the three individual miR-196 genes, as detailed below, were isolated from E9.5 mouse embryos by FACS. miR-196b knockout cells were not marked with a fluorescent reporter and an assumption of co-expression with miR-196a2 was made. mRNA profiles were generated by deep sequencing in a minimum of four biological replicates per genotype, using an Illumina HiSeq 2000 instrument. Read information was mapped to the mouse genome and processed as described. Conclusions: Our study represents the first detailed analysis of embryonic transcriptomes following loss of single and multiple miR-196 family members. We identify complex dysregulation of many Hox genes, in addition to key developmental signalling pathways involved in somitogenesis. Overall design: mRNA profiles of E9.5 mouse embryos with miR-196 loss-of-function were generated by deep sequencing, in a minimum of four biological replicates, using Illumina HiSeq 2000.
