- Illumina HumanHT-12 V4.0 expression beadchip
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.

Description
Culture medium of mesenchymal stromal cells (MSCs) is usually supplemented with either human platelet lysate (HPL) or fetal calf serum (FCS). Many studies have demonstrated that proliferation and cellular morphology is influenced by these additives hence they may favor outgrowth of specific subpopulations, thereby affecting the heterogeneous composition of MSCs. We have isolated and expanded human bone marrow derived MSCs in parallel with HPL or FCS for two passages. In HPL the proliferation was significantly higher and cells reflected more spindle-shaped morphology. Pairwise comparisons of gene expression profiles (Affymetrix HTA 2.0) revealed only moderate differences. When we apply a fold change >1.5 and limma-adjusted P-value of <0.05, only 69 transcripts were differentially expressed. These results indicate that there is no systematic bias for specific subpopulations of MSCs by using either HPL or FCS.

Description
Long non coding RNAs are implemented in epigenetic changes and regulation of gene expression. HOTAIR is a promising lncRNA concerning epigenetic regulation. We performed HOTAIR overexpression and knockdown experiments in mesenchymal stromal cells derived from bone marrow. After two weeks cells were harvested and RNA and DNA were isolated. Analysis of gene expression was performed with Human Gene 2.0 ST Array (Affymetrix, Santa Clara, USA). Analysis of DNA methylation was performed with Infinium HumanMethylation450 BeadChips (Illumina, San Diego, USA)

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
SWP73 subunits of SWI/SNF chromatin remodeling complexes (CRCs) are involved in key developmental pathways in Arabidopsis. We found, using microarray that inactivation of SWP73B caused altered expression of genes belonging to various regulatory pathways, including leaf and flower development. On the basis of this experiment and our other data we concluded that SWP73B modulates major developmental pathways.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
Zebrafish have the remarkable ability to regenerate body parts including the heart, spinal cord and fins by a process referred to as epimorphic regeneration. Recent studies have illustrated that similar to adult zebrafish, early life stage-larvae also possess the ability to regenerate the caudal fin. A comparative genomic analysis was used to determine the degree of conservation in gene expression among the regenerating adult caudal fin, adult heart and larval fin. Results indicate that these tissues respond to amputation/injury with strikingly similar genomic responses. Comparative analysis revealed raldh2, a rate-limiting enzyme for the synthesis of Retinoic acid (RA), as one of the highly induced genes across the three regeneration platforms.
