  • Comparative Analysis of Mesenchymal Stem Cell Cultivation in Fetal Calf Serum, Human Serum, and Platelet Lysate in 2D and 3D Systems 
    Kirsch, Marline; Rach, Jessica; Handke, Wiebke; Seltsam, Axel; Pepelanova, Iliyana; Strauß, Sarah; Vogt, Peter; Scheper, Thomas; Lavrentieva, Antonina (Lausanne : Frontiers Media, 2021)
    In vitro two-dimensional (2D) and three-dimensional (3D) cultivation of mammalian cells requires supplementation with serum. Mesenchymal stem cells (MSCs) are widely used in clinical trials for bioregenerative medicine and ...
  • Dispensing pico to nanolitre of a natural hydrogel by laser-assisted bioprinting 
    Gruene, Martin; Unger, Claudia; Koch, Lothar; Deiwick, Andrea; Chichkov, Boris (London : Biomed Central, 2011)
    Background: Laser-assisted bioprinting of multi-cellular replicates in accordance with CAD blueprint may substantially improve our understandings of fundamental aspects of 3 D cell-cell and cell-matrix interactions in ...
  • Femtosecond laser induced step-like structures inside transparent hydrogel due to laser induced threshold reduction 
    Saerchen, Emanuel; Liedtke-Gruener, Susann; Kopp, Maximilian; Heisterkamp, Alexander; Lubatschowski, Holger; Ripken, Tammo (San Francisco, CA : Public Library of Science (PLoS), 2019)
    In the area of laser material processing, versatile applications for cutting glasses and transparent polymers exist. However, parasitic effects such as the creation of step-like structures appear when laser cutting inside ...
  • Hydrogel-based microfluidics for vascular tissue engineering 
    Koroleva, Anastasia; Deiwick, Andrea; Nguyen, Alexander; Narayan, Roger; Shpichka, Anastasia; Kufelt, Olga; Kiyan, Roman; Bagratashvili, Victor N.; Timashev, Peter; Scheper, Thomas; Chichkov, Boris (Berlin : De Gruyter, 2016)
    In this work, we have explored 3-D co-culture of vasculogenic cells within a synthetically modified fibrin hydrogel. Fibrinogen was covalently linked with PEG-NHS in order to improve its degradability resistance and ...
  • Hydrogels based on collagen and fibrin - Frontiers and applications 
    Schneider-Barthold, Caroline; Baganz, Sabrina; Wilhelmi, Mathias; Scheper, Thomas; Pepelanova, Iliyana (Berlin : De Gruyter, 2016)
    Hydrogels are a versatile tool for a multitude of applications in biomedical research and clinical practice. Especially collagen and fibrin hydrogels are distinguished by their excellent biocompatibility, natural capacity ...
  • Iron Nanoparticle Composite Hydrogels for Studying Effects of Iron Ion Release on Red Blood Cell In Vitro Production 
    Brändle, Katharina; Bergmann, Timna C.; Raic, Annamarija; Li, Yaya; Million, Nina; Rehbock, Christoph; Barcikowski, Stephan; Lee-Thedieck, Cornelia (Washington, DC : ACS Publications, 2020-07-01)
    Growing numbers of complex surgical interventions increase the need for blood transfusions, which cannot be fulfilled by the number of donors. Therefore, the interest in producing erythrocytes from their precursors—the ...
  • Multifunktionale nanostrukturierte Hydrogele zur Kultur hämatopoetischer Stammzellen 
    Ludwig-Husemann, Anita (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2023)
    Um die funktionellen Interaktionen hämatopoetischer Stamm- und Progenitorzellen (HSPZ) mit ihrer physiologischen Nische im Knochenmark zu verstehen, sind artifizielle Nischenmodelle zur Untersuchung einzelner biochemischer ...
  • Shrinkable silver diffraction grating fabricated inside a hydrogel using 522-nm femtosecond laser 
    Machida, Manan; Nakajima, Yasutaka; Torres-Mapa, Maria Leilani; Heinemann, Dag; Heisterkamp, Alexander; Terakawa, Mitsuhiro (London : Nature Publishing Group, 2018)
    The integration of metal microstructures and soft materials is promising for the realization of novel optical and biomedical devices owing to the flexibility and biocompatibility of the latter. Nevertheless, the fabrication ...
  • Swelling and Mechanical Characterization of Polyelectrolyte Hydrogels as Potential Synthetic Cartilage Substitute Materials 
    Romischke, Johanna; Scherkus, Anton; Saemann, Michael; Krueger, Simone; Bader, Rainer; Kragl, Udo; Meyer, Johanna (Basel : MDPI, 2022)
    Hydrogels have become an increasingly interesting topic in numerous fields of application. In addition to their use as immobilization matrixes in (bio)catalysis, they are widely used in the medical sector, e.g., in drug ...
