  1. 1. Modular Hyaluronan-Based Hydrogels for 3D Cell Culture and Bioprinting

    Author : Michael Jury; Daniel Aili; Robert Selegård; My Hedhammar; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hyaluronan; 3D cell-culture; Biofunctionality; Bioprinting;

    Abstract : Three-dimensional (3D) cell culture facilitates development of biological relevant assays for drug screening and toxicity testing. Compared to conventional 2D cell culture, cells cultured in 3D can more accurately mimic human tissues and organs and thus provide ex vivo data with potentially better predictive value for cancer research, pharmacology, and toxicology, reducing the need for animal models, improving experimental reproducibility, and reducing time and costs in drug development.

  2. 2. Strength in Numbers – Droplet Microfluidics for Multicellular Ensemble Applications

    Author : Martin Trossbach; Aman Russom; Håkan Jönsson; Nicole Pamme; KTH; []
    Keywords : Droplet Microfluidics; High-Throughput Screening; Microtissues; Microreactors; Cell Factories; Cell Culture; Biomaterials; Spheroids; Biotechnology; Bioteknologi;

    Abstract : The work presented in this doctoral thesis explores multicellular, biological, and biotechnological applications for microfluidic droplets, making use of a number of unique features of these miniaturized, highly scalable reaction vessels.Droplet microfluidics specializes in pico- to nanoliter sized aqueous droplets in an immiscible oil phase, borrowing techniques from the field of microfluidics, namely fluid actuation, detection systems and electronic peripherals.

  3. 3. In vitro wound healing characteristics of amelogenins

    Author : Sofia Almqvist; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; amelogenins; extracellular matrix; cell culture; macrophage; fibroblast; endothelial cell; integrin; cytokine; inflammation; wound healing tissue repair;

    Abstract : Wound healing involves the co-ordinated actions of several cell types, soluble cell mediators and extracellular matrix (ECM). This research project intended to investigate the role of certain ECM proteins in different processes during tissue repair by studying the interaction between dermal cells and ECM. READ MORE

  4. 4. Modular Enzyme-Responsive Polysaccharide-Based Hydrogels for Biofabrication

    Author : Sajjad Naeimipour; Daniel Aili; Robert Selegård; Alireza Dolatshahi-Pirouz; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D cell-culture; Bioprinting; Alginate; Hyaluronan; Cancer model;

    Abstract : Engineered human tissue and disease models can decrease the cost and time of developing new drugs and treatments, facilitate personalized medicine, and eliminate the need for animal models that poorly represent the human body and are ethically problematic. However, the current conventional cell expansion methods using 2D culture flasks cannot enable the development of such complex multi-cellular 3D models. READ MORE

  5. 5. High-throughput screening using multicellular tumor spheroids to reveal and exploit tumor-specific vulnerabilities

    Abstract : High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. READ MORE
