Certain parameters of those types of scaffolds, however, greatly affect cellular mechanobiology and therefore the myogenic outcome. The aim of this study was to identify the influence of apparent elastic properties of fibrin scaffolds in 2D and 3D on myoblasts and evaluate if those effects differ between murine and human cells. Therefore, myoblasts were cultured on fibrin-coated multiwell plates ("2D") or embedded in fibrin hydrogels ("3D") with different elastic moduli. Firstly, we established an almost linear correlation between hydrogels' fibrinogen concentrations and apparent elastic moduli in the range of 7.5 mg/ml to 30 mg/ml fibrinogen (corresponds to a range of 7.7-30.9 kPa). The effects of fibrin hydrogel elastic modulus on myoblast proliferation changed depending on culture type (2D vs 3D) with an inhibitory effect at higher fibrinogen concentrations in 3D gels and vice versa in 2D. The opposite effect was evident in differentiating myoblasts as shown by gene expression analysis of myogenesis marker genes and altered myotube morphology. Furthermore, culture in a 3D environment slowed down proliferation compared to 2D, with a significantly more pronounced effect on human myoblasts. Differentiation potential was also substantially impaired upon incorporation into 3D gels in human, but not in murine, myoblasts. With this study, we gained further insight in the influence of apparent elastic modulus and culture type on cellular behavior and myogenic outcome of skeletal muscle tissue engineering approaches. Furthermore, the results highlight the need to adapt parameters of 3D culture setups established for murine cells when applied to human cells.}, subject = {Tissue Engineering}, language = {en} } @article{EderVoronkoDimitriadisetal., author = {Eder, Gabriele C. and Voronko, Yuliya and Dimitriadis, Simon and Kn{\"o}bl, Karl and Ujv{\´a}ri, Guszt{\´a}v and Berger, Karl A. and Halwachs, Martin and Neumaier, Lukas and Hirschl, Christina}, title = {Climate specific accelerated ageing tests and evaluation of ageing induced electrical, physical, and chemical changes}, series = {Progress in Photovoltaics: Research and Applications 2018}, journal = {Progress in Photovoltaics: Research and Applications 2018}, pages = {1 -- 16}, subject = {Photovoltaik}, language = {en} } @inproceedings{EderVoronkoDimitriadisetal., author = {Eder, C. and Voronko, Yuliya and Dimitriadis, Simon and Kn{\"o}bl, Karl and Ujv{\´a}ri, Guszt{\´a}v and Berger, Karl A. and Halwachs, Martin and Neumaier, Lukas and Hirschl, Christina}, title = {Influence of variable climatic stress conditions on performance and material degradation of PV-modules}, series = {SOPHIA PV-Reliability Workshop 2018, Ljubljana}, booktitle = {SOPHIA PV-Reliability Workshop 2018, Ljubljana}, subject = {Photovoltaics}, language = {en} } @inproceedings{EderVoronkoDimitriadisetal., author = {Eder, Gabriele C. and Voronko, Yuliya and Dimitriadis, Simon and Kn{\"o}bl, Karl and Ujv{\´a}ri, Guszt{\´a}v and Berger, Karl A. and Neumaier, Lukas}, title = {Climate Specific Accelerated Ageing Tests \& Evaluation of Ageing Induced Electrical, Physical and Chemical Changes}, series = {35th EU PVSEC 2018 5DO.7.4}, booktitle = {35th EU PVSEC 2018 5DO.7.4}, subject = {Photovoltaics}, language = {en} } @inproceedings{EderGrillbergerVoronkoetal., author = {Eder, Gabriele C. and Grillberger, Paul and Voronko, Yuliya and Kubitschek, Bernhard and Kn{\"o}bl, Karl}, title = {UV-Fluorescence measurements as tool for the detection of degradation effects in PV-modules}, series = {Proceedings of the European Weathering Symposium EWS}, booktitle = {Proceedings of the European Weathering Symposium EWS}, organization = {Gesellschaft f{\"u}r Umweltsimulation e.V.
