Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Tumor associated fibroblasts are known to play an important role in angiogenesis, however the specific signaling pathways playing an important role in this cross talk remain ill defined. Here, we studied how Ets2 transcrpiton factor signaling in tumor associated fibroblasts effected gene expression in surrounding endothelial cells in the MMTV-PyMT mammary tumor model.

Description
The mechanisms involved in epithelium-stroma interactions remain poorly understood, despite the importance of the microenvironment during tumorigenesis. Here, we studied the role of Ets2 transcrpiton factor in tumor associated fibroblasts in the MMTV-ErbB2 mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor growth, in contrast to Ets2 inactivation in epithelium in which no differences in tumor growth were observed.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
10 normal squamous cervical epitheilia samples, 7 high grade squamous intraepithelial lesions, and 21 invasive squamous cell carcinomas of the cervix samples were obtained using laser capture miicrodissection. Two rounds of T7-based linear RNA amplification using the Arcturus RiboAmp kit were performed for each sample, and assayed using Affymetrix HG_U133A arrays.

Description
We used RNA sequencing to profile over 70 transcriptomes of CD4+ T cells, a cell type crucial for Coeliac Disease CD pathogenesis, in both stimulated and resting samples from individuals with CD and unaffected controls The data gave us the opportunity to (i) compare gene expression between cases and controls; (ii) specifically assess whether genes that have been genetically associated with the disease were being DE; (iii) and also look for known and novel aspects of pathogenesis in the transcriptome of this specific cellular compartment. Overall design: RNA sequencing was performed on mRNA extracted from the CD4+ T cells of 15 Coeliac patients and 11 Controls that had been stimulated with anti-CD3/anti-CD28, PMA and left unstimulated. In total we sequenced 74 transcriptome samples using 50bp reads on an Illumina HiSeqâ„¢ 2000.

Description
Mice that are mutant for both Fgfr1 and Fgfr2 specifically in the developing retina develop coloboma. To analyze the transcripts that are affected by defective FGF signaling, we micro-dissected the optic fissure region from the control and FGFR condtional mutant mice and did microarray analysis.

Description
The development of complex tissues requires that mitotic progenitor cells integrate information from the environment. The highly varied outcomes of such integration processes undoubtedly depend at least in part upon variations among the gene expression programs of individual progenitor cells. To date, there has not been a comprehensive examination of these differences among progenitor cells of a particular tissue. Here, we used comprehensive gene expression profiling to define these differences among individual progenitor cells of the vertebrate retina. Retinal progenitor cells (RPCs) have been shown by lineage analysis to be multipotent throughout development and to produce distinct types of daughter cells in a temporal, conserved order. A total of 42 single RPCs were profiled on Affymetrix arrays. An extensive amount of heterogeneity in gene expression among RPCs, even among cells isolated from the same developmental time point, was observed. While many classes of genes displayed heterogeneity of gene expression, the expression of transcription factors constituted a significant amount of the observed heterogeneity. Additionally, the expression of cell cycle related transcripts showed differences among those associated with G2 and M, versus G1 and S phase, suggesting different levels of regulation for these genes. These data provide insights into the types of processes and genes that are fundamental to cell fate choices, proliferation decisions, and, for cells of the central nervous system, the underpinnings of the formation of complex circuitry.

Description
Identification of genes expressed in a preferential manner in the developing ciliary body/iris will provide a starting point for future functional analyses. To identify candidate genes expressed in a variety of ocular tissues during development, we have profiled single cells from the developing eye. Post hoc identification of the origin of these cells showed that they included cells from the periphery of the developing optic cup. By comparing the expression profiles of these cells to many retinal cell types, candidate genes for preferential expression in the periphery were identified.

Description
The vertebrate retina uses diverse neuronal cell types arrayed into complex neural circuits to extract, process and relay information from the visual scene to the higher order processing centers of the brain. Amacrine cells, a diverse class of inhibitory interneurons, are thought to mediate the majority of the processing of the visual signal that occurs within the retina. Despite morphological characterization, the number of known molecular markers of amacrine cell types is still much smaller than the 26 morphological types that have been identified. Furthermore, it is not known how this diversity arises during development. Here, we have combined in vivo genetic labeling and single cell genome-wide expression profiling to: 1) Identify specific molecular types of amacrine cells; 2) Demonstrate the molecular diversity of the amacrine cell class.
Publication Title
Development and diversification of retinal amacrine interneurons at single cell resolution.
