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} } @inproceedings{MaleinerHeherTeuschletal., author = {Maleiner, Babette and Heher, Philipp and Teuschl, Andreas and Redl, Heinz and R{\"u}nzler, Dominik and Fuchs, Christiane}, title = {Generation of aligned skeletal muscle-like tissue based on the application of strain to a 3D fibrin scaffold}, series = {Proceedings of PACT "Designer Cells go Clinical" Symposium}, booktitle = {Proceedings of PACT "Designer Cells go Clinical" Symposium}, subject = {Tissue Generation}, language = {en} } @misc{MaleinerHeherTeuschletal., author = {Maleiner, Babette and Heher, Philipp and Teuschl, Andreas and Redl, Heinz and R{\"u}nzler, Dominik and Fuchs, Christiane}, title = {Generation of aligned skeletal muscle-like tissue based on the application of strain to a 3D fibrin scaffold}, subject = {Tissue Generation}, language = {en} } @article{TeuschlSchuhHalbweisetal., author = {Teuschl, Andreas and Schuh, Christina and Halbweis, Robert and Pajer, Krisztian and Marton, Gabor and Hopf, Rudolf and Mosia, Shorena and R{\"u}nzler, Dominik and Redl, Heinz and Nogradi, Antal and Hausner, Thomas}, title = {A new preparation method for anisotropic silk fibroin nerve guidance conduits and its evaluation in vitro and in a rat sciatic nerve defect model}, series = {Tissue Engineering Part C: Methods}, journal = {Tissue Engineering Part C: Methods}, subject = {Fibrin}, language = {en} } @misc{TeuschlFuchsFeichtingeretal., author = {Teuschl, Andreas and Fuchs, Christiane and Feichtinger, Georg and Heher, Philipp and Heimel, Patrick and Schuh, Christina and N{\"u}rnberger, Sylvia and Nau, Thomas and R{\"u}nzler, Dominik and Redl, Heinz}, title = {Fibrin or Fibroin - Not only the "o" Makes the Difference}, subject = {Fibrin}, language = {en} } @article{TeuschlNeutschMonforteVilaetal., author = {Teuschl, Andreas and Neutsch, Lukas and Monforte Vila, Xavier and R{\"u}nzler, Dominik and van Griensven, Martijn and Gabor, Franz and Redl, Heinz}, title = {Enhanced cell adhesion on silk fibroin via lectin surface modification.}, series = {Acta Biomaterialia}, journal = {Acta Biomaterialia}, subject = {Silk}, language = {en} } @article{SchuhBanerjeeMosiaetal., author = {Schuh, Christina and Banerjee, Asmita and Mosia, Shorena and Hopf, Rudolf and Grasl, Christian and Schima, Heinrich and Schmidhammer, Robert and Redl, Heinz and R{\"u}nzler, Dominik and Morton, Tatjana J.}, title = {Activated Schwann-like cells guided by fibrin structures enhance Axonal Regeneration}, series = {JOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MEDICINE}, volume = {2012}, journal = {JOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MEDICINE}, number = {vol. 6/no. 1}, subject = {Cells}, language = {en} }
