Project description:This SuperSeries is composed of the following subset Series:; GSE5150: TGF-beta1 target genes in human hematopoietic stem/progenitor cells. GSE5151: TGF-beta1 target genes in human dendritic cells (DC). Experiment Overall Design: Refer to individual Series
Project description:CD34+ hematopoietic stem/progenitor cells were isolated from human cord blood and amplified in vitro for 10-14 days in serum-free medium with specific cytokines (Ju et al., Eur. J. Cell Biol. 82, 75-86, 2003; Hacker et al., Nat. Immunol. 4, 380-386, 2003). Cells were then treated with TGF-beta1 for various periods of time (2, 4, 16 hours) and RNA was prepared and subjected to microarray analysis. Experiment Overall Design: CD34+ hematopoietic stem/progenitor cells (HPC) were amplified in vitro and treated with TGF-beta1 (10 ng/ml) for 2, 4 and 16 hours. Experiment Overall Design: HPC untreated Experiment Overall Design: HPC + TGF-beta1 for 2 hours Experiment Overall Design: HPC + TGF-beta1 for 4 hours Experiment Overall Design: HPC + TGF-beta1 for 16 hours

J. Cell Biol. 82, 75-86, 2003; Hacker et al., Nat. Immunol. 4, 380-386, 2003). Cultured progenitor cells were induced to differentiate into DC in RPMI medium supplemented with 10% fetal calf serum, 2 mM L-glutamine, 0.1 microM Beta-mercaptoethanol, 100 U/ml penicillin and streptomycin (GIBCO-BRL) and 500 U/ml GM-CSF, 500 U/ml IL-4 for 6 days with or without 10 ng/ml TGF-beta1 as indicated (0.5x10E6 cells/ml). Every 2 days growth factors were added and cells were maintained at 0.5x10E6 cells/ml cell density. RNA was prepared and subjected to microarray analysis. Experiment Overall Design: Dendritic cells (DC) were treated for various periods of time (4, 16 and 36 hours) with TGF-beta1 (10 ng/ml) or left untreated. Experiment Overall Design: DC untreated Experiment Overall Design: DC + TGF-beta1 for 4 hours Experiment Overall Design: DC + TGF-beta1 for 16 hours Experiment Overall Design: DC + TGF-beta1 for 36 hours

Project description:Analysis of genes induced by TGF-beta1 in human lung fibroblasts. TGF-beta1 is essential for fibroblast -myofibroblast differentiation, which is a hallmark in the development of lung fibrosis. Newly identified genes up- or down-regulated by TGF-beta1 in human lung fibroblasts may serve as pharmacological target for therapeutic options in patients with lung fibrosis.
Project description:This is a mathematical model describing the hematopoietic lineages with leukemia lineages, as controlled by end-product negative feedback inhibition. Variables include hematopoietic stem cells, progenitor cells, terminally differentiated HSCs, leukemia stem cells, and terminally differentiated leukemia stem cells.
