Description
We present a gene expression atlas of early mouse craniofacial development. Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face.

Description
Laser capture microdissection (LCM) was used to isolate cells from the principal critical micro-regions, whose development, differentiation and signaling interactions are responsible for the construction of the mammalian face. At E8.5, as migrating neural crest cells begin to exit the neural fold/epidermal ectoderm boundary, we examined the facial mesenchyme, composed of neural crest and paraxial mesoderm cells, as well as cells from adjacent neuroepithelium.

Description
Purpose: To use single-cell RNA-Seq analysis of nephron progenitors in order to determine transcrptional differences as nephron progenitors age. Methods: Using a combination of FACS sorting and a Fluidigm Single-cell auto-prep system, we generated high-throughput RNA-SEQ data of nephron progenitors during development Results: Single cells transcriptome profiling of nephron progenitors revealed progressive age-dependent changes with heterogeneity increasing in older populations. Overall design: 96-single cell transcriptomes were determined from nephron progenitors of e14.5, e18.5 and P0 using Cited1GFP transgenic animals

- Affymetrix C. elegans Genome Array (celegans)
Description
Background: DNA microarrays provide a powerful method for global analysis of gene expression. The application of this technology to specific cell types and tissues, however, is typically limited by small amounts of available mRNA, thereby necessitating amplification. Here we compare microarray results obtained with two different methods of RNA amplification to profile gene expression in the C. elegans larval nervous system. Results: We used the mRNA-tagging strategy to isolate transcripts specifically from C. elegans larval neurons. The WT-Ovation Pico System (WT-Pico) was used to amplify 2 ng of Pan-neural RNA to produce labeled cDNA for microarray analysis. These WT-Pico-derived data were compared to microarray results obtained with a labeled aRNA target generated by two rounds of In Vitro Transcription (IVT) of 25 ng of Pan-neural RNA. WT-Pico results in a higher fraction of Present calls than IVT, a finding consistent with the proposal that DNA-DNA hybridization results in lower mismatch signals than the RNA-DNA heteroduplexes produced by IVT amplification. Microarray data sets from these samples were compared to a Reference profile of all larval cells to identify transcripts with elevated expression in neurons. These results were validated by the high proportion of known neuron-expressed genes detected in these profiles and by promoter-GFP constructs for previously uncharacterized genes in these data sets. Together, the IVT and WT-Pico methods identified 2,173 unique neuron-enriched transcripts. Only about half of these transcripts (1,044), however, are detected as enriched by both IVT and WT-Pico amplification.

Description
The use of induced pluripotent stem cells (iPSC) derived from independent patients and sources holds considerable promise to improve the understanding of development and disease. However, optimized use of iPSC depends on our ability to develop methods to efficiently qualify cell lines and protocols, monitor genetic stability, and evaluate self-renewal and differentiation potential. To accomplish these goals, 57 stem cell lines from 10 laboratories were differentiated to 7 different states, resulting in 248 analyzed samples. Cell lines were differentiated and characterized at a central laboratory using standardized cell culture methodologies, protocols, and metadata descriptors. Stem cell and derived differentiated lines were characterized using RNA-seq, miRNA-seq, copy number arrays, DNA methylation arrays, flow cytometry, and molecular histology. All materials, including raw data, metadata, analysis and processing code, and methodological and provenance documentation are publicly available for re-use and interactive exploration at https://www.synapse.org/pcbc. The goal is to provide data that can improve our ability to robustly and reproducibly use human pluripotent stem cells to understand development and disease.

Description
Objective: Long non-coding RNAs (lncRNA) regulate gene transcription and diverse cellular functions. We previously defined a novel core inflammatory and metabolic ileal gene signature in treatment naïve pediatric Crohn Disease (CD), however, genome-wide characterization of lncRNA expression was lacking. We now extend our analyses to define a more comprehensive view that includes lncRNA. Design: Using RNAseq, we performed a systematic profiling of lncRNAs and protein-coding genes expression in 177 ileal biopsies. Co-expression analysis was used to identify functions and tissue-specific expression. RT-PCR was used to test lncRNAs regulation by IL-1ß in Caco-2 enterocytes model. Results: We characterize a widespread dysregulation of 459 lncRNA in the ileum of treatment naïve pediatric CD patients. Unsupervised and supervised classifications using the 459 lncRNA showed comparable patients' grouping as the 2160 dysregulated protein-coding genes, linking lncRNA to CD pathogenesis. Co-expression and functional annotation enrichment analyses across several tissues and cell types showed that the up-regulated LINC01272 is associated with a myeloid pro-inflammatory signature while the down-regulated HNF4A-AS1 exhibits association with an epithelial metabolic signature. We further validated expression and regulation of prioritized lncRNA upon IL-1ß exposure in differentiated Caco-2 cells. Finally, we identified significant correlations between LINC01272 and HNF4A-AS1 expression and more severe mucosal injury. Conclusion: We define differentially expressed lncRNA in the ileum of treatment naive pediatric CD. We show lncRNA utility to correctly classify disease or healthy states and demonstrate their regulation in response to an inflammatory signal. These lncRNA, after mechanistic exploration, may serve as potential new targets for RNA-based interventions. Overall design: Using RNAseq, we performed a systematic profiling of lncRNAs and protein-coding genes expression in 21 days differentiated caco-2 cells

Description
RNA was isolated from rectal biopsies from 190 pediatric patients undergoing diagnostic colonoscopy for inflammatory bowel diseases, including Crohn's disease and ulcerative colitis. Single-end, 75-bp sequencing was performed, and raw reads aligned to the human genome using Gencode v 24 as reference. We included 14085 protein-coding mRNA genes in downstream analyses, where cutoffs of fold change>1.5 and FDR<0.05 were considered significant. Overall design: RNA-sequencing of rectal biopsies obtained from pediatric IBD and control patients.
