This book was released on 2022-04-29 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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. The most widely used options for scaffold-based 3D cell culture are, however, based on poorly defined biologically derived extracellular matrix (ECM) with limited possibilities to tailor material properties and that are difficult to combine with state-of-the art biofabrication techniques. The overall aim this thesis was to design and explore modular hyaluronan (HA) based ECM-mimicking hydrogels with tuneable physiochemical properties and biofunctionalities, for development of advanced 3D cell models and biofabrication. The thesis work is presented in five papers. In paper I, we used copper free click chemistry for both hydrogel cross-linking and functionalization with fibronectin derived peptide sequences for culture of human induced pluripotent-derived hepatocytes in a perfused microfluidic system. The tuneable and bioorthogonal cross-linking enabled both retention of high cell viabilities and fabrication of a functional liver-on-chip solution. In paper II, we combined the developed HA-based hydrogel system with homo- and heterodimerizing helix-loop-helix peptides for modulation of both cross-linking density and biofunctionalization. We further demonstrated the possibilities to use these hydrogels as bioinks for 3D bioprinting where both the molecular composition and the physical properties of the printed structures could be dynamically altered, providing new avenues for four-dimensional (4D) bioprinting. In paper III we investigated the possibilities to chemically conjugate full size recombinant human laminin-521 (LN521) in the HA-based hydrogels system using copper-free click chemistry, with the aim to enable 3D culture and 3D bioprinting of neurons. We quantified the impact of using different linkers to tether LN521 and the influence of LN-functionalization on the structural and mechanical properties of the hydrogels. We show that both differentiated and non-differentiated neuroblastoma cells and long-term self-renewing neuroepithelial stem cells (lt-NES) remained viable in the hydrogels. The hydrogels also had a protected effect on lt-NES during syringe ejection and bioprinting. In paper IV, we used HA-based hydrogels modified with peptides sequences derived from fibronectin and laminin for culture of fetal primary astrocytes (FPA). We explored both the interactions between the hydrogels and FPA and possibilities to 3D bioprint FPAs. Finally, in paper V, we developed HA-nanocellulose composite hydrogels with the aim to increase printing fidelity and enable fabrication of multi-layered bioprinted structures without the use of a support bath. In addition to HA, we used wood-fibre derived nanocellulose (NC) to increase the viscosity of the bioink during the printing process. The developed biorthogonal and modular hydrogel systems provide a large degree of flexibility that allows for encapsulation and culture of different cell types and processing using different techniques, which can contribute to further exploration of fabrication of biologically relevant tissue and disease models.

Download or read book Inkjet Technology for Digital Fabrication written by Ian M. Hutchings and published by John Wiley & Sons. This book was released on 2012-11-09 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whilst inkjet technology is well-established on home and small office desktops and is now having increasing impact in commercial printing, it can also be used to deposit materials other than ink as individual droplets at a microscopic scale. This allows metals, ceramics, polymers and biological materials (including living cells) to be patterned on to substrates under precise digital control. This approach offers huge potential advantages for manufacturing, since inkjet methods can be used to generate structures and functions which cannot be attained in other ways. Beginning with an overview of the fundamentals, this bookcovers the key components, for example piezoelectric print-heads and fluids for inkjet printing, and the processes involved. It goes on to describe specific applications, e.g. MEMS, printed circuits, active and passive electronics, biopolymers and living cells, and additive manufacturing. Detailed case studies are included on flat-panel OLED displays, RFID (radio-frequency identification) manufacturing and tissue engineering, while a comprehensive examination of the current technologies and future directions of inkjet technology completes the coverage. With contributions from both academic researchers and leading names in the industry, Inkjet Technology for Digital Fabrication is a comprehensive resource for technical development engineers, researchers and students in inkjet technology and system development, and will also appeal to researchers in chemistry, physics, engineering, materials science and electronics.

Book excerpt: The aim of this Special Issue is to review, understand, and evaluate new and exciting opportunities from the field on regenerative medicine, biomaterials, and stem cell research for the bioengineering of human liver grafts that can be applied for transplantation and personalized treatment of end-stage liver disease.The development of culture conditions for long-term expansion of LGR5+ intestinal stem cells as crypt-villus structures demonstrated the feasibility of deriving complex, organ-like structures in vitro from primary adult tissues, including the liver. Moreover, human pluripotent stem cells (hPSCs) can be applied to generate functionally maturated liver and bile duct epithelial cells.In this Special Issue, we welcome reviews and original papers focussing on hepatic cell sources, including adult hepatic stem cells, organoids, fetal and induced pluripotent stem cells, and primary cells (i.e., hepatocytes, cholangiocytes, and endothelial cells) and how these cells can be applied in tissue engineering strategies to generate implantable and personalized liver grafts. Potential topics include, but are not limited to, the following: liver tissue engineering, liver regeneration, graft repair, liver stem cells and organoids, bio-scaffolds, and 3D printing.We invite you to contribute original research papers, as well as comprehensive reviews, aligned with these themes, to advance and improve the actual state-of-the-art in liver bioengineering and providing new opportunities for the imminent medical problem of organ and tissue shortage for transplantation.

Download or read book Tumor Organoids written by Shay Soker and published by Humana Press. This book was released on 2017-10-20 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer cell biology research in general, and anti-cancer drug development specifically, still relies on standard cell culture techniques that place the cells in an unnatural environment. As a consequence, growing tumor cells in plastic dishes places a selective pressure that substantially alters their original molecular and phenotypic properties.The emerging field of regenerative medicine has developed bioengineered tissue platforms that can better mimic the structure and cellular heterogeneity of in vivo tissue, and are suitable for tumor bioengineering research. Microengineering technologies have resulted in advanced methods for creating and culturing 3-D human tissue. By encapsulating the respective cell type or combining several cell types to form tissues, these model organs can be viable for longer periods of time and are cultured to develop functional properties similar to native tissues. This approach recapitulates the dynamic role of cell–cell, cell–ECM, and mechanical interactions inside the tumor. Further incorporation of cells representative of the tumor stroma, such as endothelial cells (EC) and tumor fibroblasts, can mimic the in vivo tumor microenvironment. Collectively, bioengineered tumors create an important resource for the in vitro study of tumor growth in 3D including tumor biomechanics and the effects of anti-cancer drugs on 3D tumor tissue. These technologies have the potential to overcome current limitations to genetic and histological tumor classification and development of personalized therapies.
