The protective function of EPS plays an important role in the survival of microalgae in polluted habitats. So far, the particular biological and physico-chemical properties of EPS have not been adequately investigated and their effect on cells such as human chondrocytes has not been tested. Microalgae in particular offer an ideal platform for the production of dietary supplements or drugs that enable new therapeutic approaches. METHODS: To investigate the influence of EPS on human chondrocytes, cytotoxicity and differentiation potential were analyzed in 3D cultures. RESULTS: We were able to demonstrate a positive, but donor-specific influence of EPS on the differentiation of human chondrocytes. Furthermore, the EPS showed no cytotoxic effects in a range of up to 250 µg EPS per ml medium. CONCLUSION: EPS have the potential to positively influence the differentiation of human chondrocytes. Further experiments are necessary to analyze the donor-specific effect.}, language = {en} } @misc{EckeScholkaHanschetal., author = {Ecke, Annemarie and Scholka, Jenny and Hansch, Anna and Becker, Roland and Anderer, Ursula}, title = {Differentiation of human articular chondrocytes in microtissues depends on the cell aggregation technique}, pages = {1}, language = {en} } @inproceedings{LehmannMartinScholkaetal., author = {Lehmann, Mario and Martin, Frank and Scholka, Jenny and Petto, Carola and Wittenburg, Gretel and Sack, Ulrich and Anderer, Ursula}, title = {Human chondrocytes and dental pulp stem cells enhance their chondrogenic differentiation potential via a two-step fusion culture technique}, series = {Tissue Engineering, Part A, Vol. 21, Suppl. 1}, booktitle = {Tissue Engineering, Part A, Vol. 21, Suppl. 1}, doi = {10.1089/ten.tea.2015.5000.abstracts}, pages = {S-268 -- S-269}, language = {en} } @inproceedings{LutterHempelDieteretal., author = {Lutter, Anne-Helen and Hempel, Ute and Dieter, Peter and Anderer, Ursula}, title = {Cost-efficient diagnostic platform to measure osteoclast activity}, series = {35.

Here, we demonstrate that the expression levels of the transcriptional repressor TRPS1 are specifically enhanced in the embryonal subtype, resulting in impaired terminal myogenic differentiation and tumor growth. During normal myogenesis, expression levels of TRPS1 have to decrease to allow myogenic progression, as demonstrated by overexpression of TRPS1 in myoblasts impairing myotube formation. Consequentially, myogenic differentiation in embryonal rhabdomyosarcoma in vitro as well as in vivo can be achieved by reducing TRPS1 levels. Furthermore, we show that TRPS1 levels in RD cells, the bona fide model cell line for embryonal rhabdomyosarcoma, are regulated by miR-1 and that TRPS1 and MYOD1 share common genomic binding sites. The myogenin (MYOG) promoter is one of the critical targets of TRPS1 and MYOD1; we demonstrate that TRPS1 restricts MYOG expression and thereby inhibits terminal myogenic differentiation. Therefore, reduction of TRPS1 levels in embryonal rhabdomyosarcoma might be a therapeutic approach to drive embryonal rhabdomyosarcoma cells into myogenic differentiation, thereby generating postmitotic myotubes.}, language = {en} } @misc{HiemannRoggenbuckSacketal., author = {Hiemann, Rico and Roggenbuck, Dirk and Sack, Ulrich and Anderer, Ursula and Conrad, Karsten}, title = {Die HEp-2-Zelle als Target f{\"u}r multiparametrische Autoantik{\"o}rperanalytik - Automatisierung und Standardisierung/The HEp-2 cell as target for multiparametric autoantibody analyses: automation and standardisation}, series = {Journal of Laboratory Medicine}, volume = {35}, journal = {Journal of Laboratory Medicine}, number = {6}, issn = {1439-0477}, doi = {10.1515/JLM.2011.053}, pages = {351 -- 361}, abstract = {Trotz Einf{\"u}hrung von Multiplex-Assays ist die Bestimmung von Autoantik{\"o}rpern (AAK) mittels indirekter Immunfluoreszenz (IIF) nach wie vor ein wesentlicher Bestandteil der Autoimmundiagnostik.
