Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
Development of T-cells provides a unique opportunity to study cell-fate determination due to the accessability and the well defined stages of development. In order to understand the genetic programs underlying fetal and adult Tcell fate specification we subjected highly purified fetal and adult T-cell progenitor populations to a genomewide transcriptional analysis. The aim was to identify molecular elements that govern T-cell fate specification as a whole but ultimately to isolate elements that were specific for a given population in a specific developmental window.

Description
Background: The FACEBASE consortium was established in part to create a central resource for craniofacial researchers. One purpose is to provide a molecular anatomy of craniofacial development. To this end we have used a combination of laser capture microdissection and RNA-Seq to define the gene expression programs driving development of the murine palate. Results: We focused on the E14.5 palate, soon after medial fusion of the two palatal shelves. The palate was divided into multiple compartments, including medial and lateral, as well as oral and nasal, for both the anterior and posterior domains. A total of 25 RNA-Seq datasets were generated. The results provide a comprehensive view of the region specific expression of all transcription factors, growth factors and receptors. Paracrine interactions can be inferred from flanking compartment growth factor/receptor expression patterns. The results are validated primarily through very high concordance with extensive previously published gene expression data for the developing palate. In addition selected immunostain validations were carried out. Conclusions: This report provides an RNA-Seq based atlas of gene expression patterns driving palate development at microanatomic resolution. This FACEBASE resource is designed to fuel discovery by the craniofacial research community. Overall design: Laser capture microdissection and RNA-seq were used to generate gene expression profiles of different compartments of the mouse E14.5 developing palate

Description
Single cell RNA-seq is a powerful methodology, but with important limitations. In particular, the process of enzymatic separation of cells at 37O C can be expected to result in artifact changes in gene expression patterns. We here describe a dissociation method that uses protease from a psychrophilic microorganism with high activity in the cold. The entire procedure is carried out at 6O C or colder, where mammalian transcriptional machinery is largely inactive. To test this method we carry out single cell RNA-seq on about 9,000 cells, comparing the results of the cold method with a method using 37O C incubations for multiple times. We show that the cold active protease method results in a great reduction in gene expression artifacts. Overall design: Whole mouse post natal day 1 kidney cells were dissassociated by either a cold active protease or an enzyme cocktail for varying lengths of time. The gene expression profiles of the four groups of cells were determined by drop-seq / RNA-seq.

Description
We characterize the gene expression changes which occur in the mouse glomerular podocyte, mesangial, and endothelial cells between control mice and mutant mice which are missing two copies of Fyn-proto oncogene (Fyn) and one copy of CD2-associated protein (CD2AP) in a mouse model of FSGS. Overall design: The glomeruli are purified by digestion with Collagenase A and sieving, a single cell suspension is generated via enzymatic dissociation; the single cell suspension is then FACS sorted based on GFP-fluorescence (targeting the glomerular endothelial, mesangial, and podocyte cells). Total RNA was purified using a column-based system. RNA was then quantitatively and qualitatively analyzed using an agilent bioanalynzer, cDNA libraries were generated using Nugen Ovation RNA-Seq V2, and the resulting libraries were ran on an Illumina HiSeq 2500. Data was analyzed using Strand NGS version 2.6.
