Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
We here compared gene expression profiles in HepG2 cells upon stimulation with 1 ng/ml TGF-beta1 for 20 min, 1 hour, 2 hours, 4 hours, and 24 hours with untreated control cells. Experiments were done in three independent replicates. The goal of this study was to determine genes regulated by TGF-beta1.HepG2 cells were obtained from DSMZ (Braunschweig, Germany) and cell identity confirmed by STR profiling using the AmpFlSTR Identfiler Direct PCR Amplification kit (Life Technologies, Darmstadt, Germany). Gene expression profiles were compared at indicated time points after stimulation with TGF-beta (1 ng/ml) using the Human Gene 1.0 ST arrays (Affymetrix). In total 18 hybridizations are included in this series.

Description
Induced pluripotent stem cells (iPSCs) can be differentiated toward mesenchymal stromal cells (MSCs), but at least on epigenetic level this transition remains incomplete with the current culture conditions. Hydrogels provide a more physiologic three-dimensional environment for in vitro cell culture than conventional tissue culture plastic (TCP). In this study, we followed the hypothesis that growth and differentiation of primary MSCs and of iPSC-derived MSCs (iMSCs) can be enhanced on hydrogels. To this end, we used a hydrogel made of human platelet lysate (hPL). MSCs were effectively cultured on and inside hPL-gel and demonstrated more structured deposition of extracellular matrix (ECM) components than TCP. Furthermore, hPL-gel supported differentiation of iPSCs toward MSCs. Unexpectedly, the differentiation process seemed to be hardly affected by the substrate: iMSCs generated either on TCP or hPL-gel did not reveal differences in morphology, immunophenotype, or differentiation potential. Moreover, global gene expression and DNA-methylation profiles were almost identical in iMSCs generated on TCP or hPL-gel. Our results indicate that matrix elasticity is less crucial for directed lineage-specific differentiation toward MSCs than expected.

- Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Mesenchymal stromal cells (MSC) were isolated from human bone marrow. Here, we have compared gene expression profiles of MSC at early and late passages and upon stimulation with transforming growth factor beta 1 (TGF-b1). Stimulation was performed with 1ng/mL TGF-b1 for 1, 4, or 12 hours as indicated. The goal of this study was to determine if senescence-associated gene expression changes and TGF-b1 induced gene expression changes are related.
Publication Title
TGF-beta1 does not induce senescence of multipotent mesenchymal stromal cells and has similar effects in early and late passages.

Description
The de novo DNA methyltransferase 3A (DNMT3A) plays a pivotal role in hematopoietic differentiation. In this study, we followed the hypothesis that alternative splicing of DNMT3A has characteristic epigenetic and functional sequels. Various transcripts of DNMT3A were either knocked down or overexpressed in human hematopoietic stem and progenitor cells resulting in complementary and transcript-specific DNA methylation (DNAm) and gene expression changes. Our results demonstrate that different splice variants of DNMT3A have distinct epigenetic and functional sequels.
