Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Various substances have been reported to enhance the cardiac differentiation of embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). Ascorbic Acid had a cardiogenic effect in mESC CGR8 cell line. Transcriptome of AA-treated CGR8 ESCs did not reveal any significant changes in gene expression as compared to untreated cells.

Description
Plasmacytoid dendritic cells (pDCs) are an immune subset devoted to the production of high amounts of type 1 interferons in response to viral infections. While conventional dendritic cells (cDCs) originate mostly from a common dendritic cell progenitor (CDP), pDCs have been shown to develop from both CDPs and common lymphoid progenitors (CLP). Here we found that pDCs developed predominantly from IL7R+ lymphoid progenitor cells. Expression of SiglecH and Ly6D defined pDC lineage commitment along the lymphoid branch. Transcriptional characterization of SiglecH+Ly6D+ precursors indicated that pDC development requires high expression of the transcription factor IRF8, while pDC identity relies on TCF4. RNA sequencing of IL7R+ lymphoid and CDP-derived pDCs mirrored the heterogeneity of mature pDCs observed by single-cell analysis. Both mature pDC subsets are able to secrete type 1 interferons, but only myeloid-derived pDCs share with cDCs their ability to process and present antigen. Overall design: Bulk RNA Seq was performed from sort purified DN, SP and DP lymphoid progenitors and BM pDCs of 4 individual mice

Description
Pax6 is a highly conserved transcription factor among vertebrates and is important in various aspects of the central nervous system (CNS) development. However, the gene regulatory circuitry of Pax6 underlying these functions remains elusive. We find that, following expression in neural progenitor cells, Pax6 targets many promoters embedded in an active chromatin environment. Intriguingly, many of these sites are also bound by another progenitor factor, Sox2, which cooperates with Pax6 in gene regulation. A combinatorial analysis of Pax6 binding dataset with transcriptome changes in Pax6-deficient neural progenitors reveals a dual role for Pax6, in which it activates the neuronal (ectodermal) genes while concurrently represses the mesodermal and endodermal genes thereby ensuring the unidirectionality of lineage commitment towards glutamatergic neuronal differentiation. Furthermore, Pax6 is critical for inducing activity of transcription factors that elicit neurogenesis and repress others that promote non-neuronal lineages. In addition to many established downstream effectors, Pax6 directly binds and activates a number of genes that are specifically expressed in neural progenitors but have not been previously implicated in neurogenesis. The in utero knockdown of one such gene, Ift74, during brain development impairs polarity and migration of new-born neurons. These findings demonstrate new aspects of the gene regulatory circuitry of Pax6, revealing how it functions to control neuronal development at multiple levels to ensure unidirectionality and proper execution of the neurogenic program.

Description
Although recent studies support regenerative potential based on cardiac progenitor cells (CPCs), it remains unclear what cues regulate CPC fate. Using 2- and 3D-culture models, we demonstrate that the two most abundantly expressed matrix proteins in the heart, laminin and fibronectin, have opposite roles in CPC fate decision. CPCs on fibronectin showed predominantly nuclear localization of the transcriptional co-activator YAP and maintained proliferation. In contrast, seeding on laminin induced cytosolic retention and degradation of YAP and altered gene expression, which preceded decreased proliferation and enhanced lineage commitment. RNA-sequencing identified Plk2 as candidate target gene of YAP. Plk2 expression depended on YAP stability, was rapidly downregulated on laminin, and its regulation was sufficient to rescue and/or mimic the CPC response to laminin and fibronectin, respectively. These findings propose a novel role of Plk2 and identify an early molecular mechanism in matrix-instructed CPC fate with potential implications for therapeutic cardiac regeneration. Overall design: Expression profiling of cardiac progenitor cells in suspension and cultured on dishes coated with laminin or fibronectin or on non-coated dishes (biological triplicates each)
