Vitamin C Promotes Positive Selection of Mouse T Cells

ABSTRACT: We discovered that vitamin C (ascorbic acid) is required for differentiation of mouse bone marrow-derived progenitor cells in T cell cultures based on OP9-DL1 stromal cells. This microarray dataset evaluates differential expression of genes in OP9-DL1 stromal cells as well as in lymphocytes developing in the cultures when a stabilized form of ascorbic acid (l-ascorbic acid 2-phosphate; pAsc) is added. Cultures were maintained in the absence of pAsc for 13 days, at which time 800 micromolar pAsc was added. Cells were harvested after 24 and 72 hours (24 hours only in the case of OP9-DL1 cells) and solubilized in Trizol.

Notch signaling facilitates in vitro generation of cross-presenting classical dendritic cells

Project description:The IRF8-dependent subset of classical dendritic cells (cDC), termed cDC1, is important for cross-priming cytotoxic T cell responses against pathogens and tumors. Culture of hematopoietic progenitors with DC growth factor Flt3 ligand (Flt3L) yields very few cDC1 (in humans) or only immature "cDC1-like" cells (in the mouse). We report that OP9 stromal cells expressing Notch ligand Delta-like 1 (OP9-DL1) optimize Flt3L-driven development of cDC1 from murine immortalized progenitors and primary bone marrow cells. Co-culture with OP9-DL1 induced IRF8-dependent cDC1 with the phenotype (CD103+ Dec205+ CD8α+) and expression profile resembling ex vivo cDC1. OP9-DL1-induced cDC1 showed preferential migration towards Ccr7 ligands in vitro and superior T cell cross-priming and antitumor vaccination in vivo. Co-culture with OP9-DL1 also greatly increased the yield of IRF8-dependent CD141+ cDC1 from human bone marrow progenitors cultured with Flt3L. Thus, Notch signaling optimizes cDC generation in vitro and yields authentic cDC1 for functional studies and therapeutic applications.

Genes regulated by the gamma secretase inhibitor in WT and Ikaros deficient DN3 cells

Project description:Lineage-negative thymocytes were cultured on OP9-DL1 stromal cells for 16h in the presence of DMSO or the gamma secretase inhibitor MRK-003. DN3 cells cells were then sorted and their transcriptome analyzed.

A Notch ligand, Delta-like 1 functions as an adhesion molecule for mast cells

Project description:To assess the effect of over-expression of Delta-like 1 on OP9 cells on gene expression in terms of Notch signaling and adhesion molecules, gene expressions of OP9, OP9-GFP (carrying GFP gene) and OP9-DL1 (carrying GFP and DL1 gene) cells (Immunity 2002;17:749-756) were analyzed.

Mouse Bone-marrow Stromal Cell Lines Genetic Expression Comparison

Project description:OP9 stromal cells are strong inducers of mesoendodermal differentiation of human embryonic stem cells. They acquire inductive function after prolonged post-confluence culture. The experiment is designed to determine the genes specifically expressed in these highly inductive OP9 cells compared to non-confluent OP9 cultures as well as other stromal cell lines (MS5, S17).

Murine CD8+ T cells: in vitro-derived vs. thymocytes

Project description:Transcriptional profiling of mouse in-vitro derived CD8+ cells (obtained after culturing BM-HSCs isolated from B6 mice) with OP9-DL1 cells for 35 days were compared to CD8+ thymocytes isolated from 4-5 weeks old B6 mice. Our goal was to determine similarities and differences in gene expression profile between in vitro-derived CD8+ cells and CD8+ cells isolated from the thymus. The procedure of in vitro differentiation of HSC using OP9-DL1 cocultures was previously described by: Schmitt, T. M., and J. C. Zuniga-Pflucker. 2002.
