Dynamic Gene Expression Response to TGF-b Stimulation in Multipotent Progenitors and Common Dendritic Cell Progenitors

ABSTRACT: Multipotent progenitors (MPP) and common dendritic cell progenitors (CDP) were obtained from mouse bone marrow, followed by in vitro culture with a specific cytokine cocktail and FACS sorting (Felker et al., 2010; Sere et al., 2012). Cells were treated with 10 ng/ml recombinant human TGF-b1 (R&D Systems, Minneapolis, USA) for 2, 4, 8, 12 and 24 h as described (Felker et al., 2010) or left untreated. Untreated multipotent progenitor (MPP) - MPP_0h_1 - MPP_0h_2 - MPP_0h_3 TGF-beta1 treated (2 hours) MPP - MPP_2h_1 - MPP_2h_2 - MPP_2h_3 TGF-beta1 treated (4 hours) MPP - MPP_4h_1 - MPP_4h_2 - MPP_4h_3 TGF-beta1 treated (8 hours) MPP - MPP_8h_1 - MPP_8h_2 - MPP_8h_3 TGF-beta1 treated (12 hours) MPP - MPP_12h_1 - MPP_12h_2 - MPP_12h_3 TGF-beta1 treated (24 hours) MPP - MPP_24h_1 - MPP_24h_2 - MPP_24h_3 Untreated common dendritic cell progenitor (CDP) - CDP_0h_1 - CDP_0h_2 - CDP_0h_3 TGF-beta1 treated (2 hours) CDP - CDP_2h_1 - CDP_2h_2 - CDP_2h_3 TGF-beta1 treated (4 hours) CDP - CDP_4h_1 - CDP_4h_2 - CDP_4h_3 TGF-beta1 treated (8 hours) CDP - CDP_8h_1 - CDP_8h_2 - CDP_8h_3 TGF-beta1 treated (12 hours) CDP - CDP_12h_1 - CDP_12h_2 - CDP_12h_3 TGF-beta1 treated (24 hours) CDP - CDP_24h_1 - CDP_24h_2 - CDP_24h_3

<h4>Background</h4>The TGF-β signaling pathway is a fundamental pathway in the living cell, which plays a key role in many central cellular processes. The complex and sometimes contradicting mechanisms by which TGF-β yields phenotypic effects are not yet completely understood. In this study we investigated and compared the transcriptional response profile of TGF-β1 stimulation in different cell types. For this purpose, extensive experiments are performed and time-course microarray data are gener ...[more]

Project description:Dendritic cells (DCs) in lymphoid tissue comprise conventional DCs (cDCs) and plasmacytoid DCs (pDCs) that develop from common DC progenitors (CDPs). CDPs are Flt3+c-kitintM-CSFR+ and reside in bone marrow. Here we describe a two-step culture system that recapitulates DC development from c-kithiFlt3-/lo multipotent progenitors (MPPs) into CDPs and further into cDC and pDC subsets. MPPs and CDPs are amplified in vitro with Flt3 ligand, stem cell factor, hyper-IL-6 and insulin- like growth factor-1. The four-factor cocktail readily induces self-renewal of MPPs and their progression into CDPs and has no self-renewal activity on CDPs. The amplified CDPs respond to all known DC poietins and generate all lymphoid tissue DCs in vivo and in vitro. Additionally, in vitro CDPs recapitulate the cell surface marker and gene expression profile of in vivo CDPs and possess a DC-primed transcription profile. Transforming growth factor-Î²1 (TGF-Î²1) impacts on CDPs and directs their differentiation towards cDCs. Genome-wide gene expression profiling of TGF-Î²1-induced genes identified transcription factors, such as interferon regulatory factor-4 (IRF-4) and RelB, that are implicated as instructive factors for cDC subset specification. TGF-Î²1 also induced the transcription factor inhibitor of differentiation/DNA binding 2 (Id2) that suppresses pDC development. Thus, TGF-Î²1 directs CDP differentiation into cDC by inducing both cDC instructive factors and pDC inhibitory factors. 20 samples in total.
