923. Bioprinting high cell-density tissue models through spheroid fusion in self-healing hydrogels

Daly, Andrew (Biomedical Engineering, and CÚRAM, at the National University of Ireland, Galway, Ireland)

28/06/2022, 15:30

invited lecture

"Cellular models are needed to study human development and disease in vitro, and to screen drugs for toxicity and efficacy. Current approaches are limited in the engineering of functional tissue models with requisite cell densities and heterogeneity to appropriately model cell and tissue behaviors. This talk will describe how spheroid bioprinting in suspension baths can be used to engineer...

54. 3D printed anisotropic and porous dense collagen hydrogels to model skeletal muscle extracellular matrix

Camman, Marie (Sorbonne Université, CNRS, UMR 7574, Laboratoire de Chimie de la Matière Condensée de Paris)

28/06/2022, 15:50

podium presentation

*Introduction: Despite the crucial role of the muscle extracellular matrix in the organotypic organization and the transmission of mechanical force, most 3D muscle models do not mimic its specific characteristics, namely its biochemical composition, stiffness, anisotropy and porosity. In vivo, muscle extracellular matrix possesses specific characteristics such as a high amount of aligned...

55. CHEMICALLY FUNCTIONALIZABLE AND MECHANICALLY TUNABLE BIOMATERIAL FOR EMBEDDED 3D BIOPRINING

Becker, Malin Lea (Leijten Laboratory, Department of Developmental BioEngineering, TechMed Centre, University of Twente)

28/06/2022, 16:00

podium presentation

INTRODUCTION: Embedded 3D bioprinting is a promising approach to engineer complex tissues such as patterned or pre-vascularized tissue constructs1,2. However, the resulting tissue constructs are often mechanically weak, unable to form mechanical or chemical gradients, and lack on-demand tunability. Here, we report on dual crosslinkable dextran-based hydrogel as a hydrogel bath for embedded...

157. High resolution light-based 3D printing of cell-laden bio constructs

Madrid-Wolff, Jorge (EPFL )

28/06/2022, 16:20

podium presentation

3D printing has revolutionized the manufacturing of volumetric components and structures in many areas. Several fully volumetric light-based techniques have been recently developed thanks to the advent of photocurable resins, promising to reach unprecedented short print time (down to a few tens of seconds) while keeping a good resolution (around 100 microns). However, these new approaches only...

56. Magnetically-Assisted 3D Bioprinting of Tissue Engineered Tendons

Pardo Montero, Alberto (3B's Research Group )

28/06/2022, 16:30

podium presentation

Introduction:
Tendon tissues have highly-anisotropic physical properties that are responsible for its biomechanical performance and biological organization. The recreation of its 3D extracellular matrix (ECM) and cellular patterns in bioengineered constructs remains challenging. The concept of magnetically-assisted 3D bioprinting with magnetic hydrogel bioinks can be exploited to fabricate...

858. Development of bioprinted osteochondral tissue: an in-vitro model for drug discovery

Jahangir, Shahrbanoo (AO Research Institute )

28/06/2022, 16:40

podium presentation

Introduction: Osteochondral (OC) disorders like osteoarthritis (OA) and rheumatoid arthritis (RA) damage the joint's cartilage and subchondral bone. Their treatment remains a significant challenge for both researchers and orthopedics. In vitro models of OC tissue have become an essential tool to help investigate pathogenesis, develop drug screening, and test potential therapeutic approaches....
