Affymetrix Murine Genome U74A Version 2 Array (mgu74av2)
Description
HSC (Sca+ SP) were isolated from 8-12 week C57B6 mice at various time points after treatment with 5-Fluorouracil. RNA was isolated from 50,000-100,000 FACS sorted cells and subjected to two rounds of T7 based linear amplification using Ambion's Message Amp kit. Two replicates from each time point were analyzed.

Description
This scRNA-seq data is an integral part of a manuscript with the above title. Using computational methods, we were able to reconstruct a detailed branched trajectory reflecting pancreatic endocrine differentiation in the mouse embryo. Analysis of the transcriptional changes occuring during the differentiation suggested that epithelial-to-mesenchymal transition likely plays no role in this process, contrary to the prevailing dogma. Our findings were corroborated with high-resolution imaging of the developing pancreas, revealing how differentiating endocrine progenitors migrate in cohesion, forming bud-like islet precursors, or "peninsulas", and that spatiotemporal collinearity during differentiation leads to the typical core-mantle architecture of the mature, spherical islet. This work led to a complete overhaul of our understanding of how pancreatic islets are developed, laying the ground for the generation of entire islets in vitro as a potential novel source of islet transplantation. Overall design: Single-cell suspensions were prepared from pancreata of Neurogenin 3-eGFP mouse embryos sacrificed at different days of embryonic development. Single eGFP-positive cells were FACS-sorted into 96-well plates, and single-cell cDNA was prepared using the SMART-seq protocol. Single-cell sequencing libraries were generated using the Nextera XT DNA library preparation kit and sequenced on an Illumina HiSeq sequencer. Reads were aligned to the mouse reference genome build mm10 with TopHat, and single-cell gene expression profiles were computed using Cufflinks.

Description
SV40 transforms cells through the action of two oncoproteins, large T antigen and small t antigen. Small t antigen targets phosphatase PP2A, while large T antigen stimulates cell proliferation and survival by action on multiple proteins, including the tumor suppressors Rb and p53. Large T antigen also binds components of the transcription initiation complex and several transcription factors. We examined global gene expression in SV40-transformed mouse embryo fibroblasts, and in enterocytes obtained from transgenic mice. SV40 transformation alters the expression of approximately 800 cellular genes in both systems. Much of this regulation is observed in both MEFs and enterocytes and is consistent with T antigen action on the Rb-E2F pathway. However, the regulation of many genes is cell-type specific, suggesting that unique signaling pathways are activated in different cell types upon transformation, and that the consequences of SV40 transformation depends on the type of cell targeted.

Description
T lymphocytes are essential contributors to the adaptive immune system and consist of multiple lineages that serve various effector and regulatory roles. As such, precise control of gene expression is essential to the proper development and function of these cells. Previously, we identified Snai2 and Snai3 as being essential regulators of immune tolerance partly due to the impaired function of CD4+ regulatory T cells in Snai2/3 conditional double knockout mice. Here we extend those previous findings using a bone marrow transplantation model to provide an environmentally unbiased view of the molecular changes imparted onto various T lymphocyte populations once Snai2 and Snai3 are deleted. The data presented here demonstrate that Snai2 and Snai3 transcriptionally regulate the cellular fitness and functionality of not only CD4+ regulatory T cells but effector CD8a+ and CD4+ conventional T cells as well. This is achieved through the modulation of gene sets unique to each cell type and includes transcriptional targets relevant to the survival and function of each T cell lineage. As such, Snai2 and Snai3 are essential regulators of T cell immunobiology. Overall design: GFP- CD3e+ CD8a+ CD4-, GFP- CD3e+ CD8a- CD4+ CD25- and GFP- CD3e+ CD8a- CD4+ CD25+ T cells were isolated from spleens of UBC-GFP mice transplanted with WT or cDKO lineage-depleted donor bone marrow following lethal irradiation of recipient mice. RNA-seq was performed on 3-4 biological replicates from each genotype for all T cell populations analyzed.
