ACTA ‐ Department of Oral Cell Biology
Models: Joint‐on‐Chip, Bone‐on‐Chip and Broken‐Bone‐on‐Chip Researchers: Prof. dr. Jenneke Klein‐Nulend and Dr. Astrid Bakker Bone is highly mechanosensitive tissue and mechanical loading is a strong stimulus for bone
remodelling and osteogenesis. Mechanical loading has a direct on effect on cellular responses by cellular and nuclear deformation as well an indirect effect by modulation of the expression of growth factors and cytokines. Based on a long record of research into mechanotransduction this group is currently working on 3 organ‐on‐Chip models which include different cell types and physico‐chemical cues.
Facilities: ML1 and ML2 cell culture labs with experimental equipment to apply fluid shear stress,cyclic tensile stretch and pressure.

Researchers: Prof. dr. Sue Gibbs and Prof. Floris Bikker. Our mouth is inhabited by abundant microbes which continuously interact with the soft tissues within our mouth such as our oral mucosa (gingiva). Such mucosa‐microbe interactions play important roles in oral health and disease. Also, we often have dental implants or fillings to replace or repair our damaged teeth. In the lab we have engineered pieces of living oral mucosa in 3D which consists of a reconstructed gingiva epithelium containing Langerhans Cells on a fibroblast populated hydrogel. This organotypic gingiva is used to investigate interactions with healthy and pathogenic microbes and also to investigate potential adverse effects caused by materials contained within implants and fillings. Systemic immune responses are investigated using OoC technology (TissUse).

Models: 2D myotube and muscle stem cell models with integrated mechanical loading devices Researchers: Prof. dr. Richard Jaspers and Dr. Rob Wüst
Muscle function is largely determined by myofiber size and oxidative capacity. We aim to uncover optimal physico‐chemical cues for myogenesis, adapation of myofiber size as well as mitochondrial biosynthesis and function. Our current models are currently 2D, but we would like to collaborate with hDMT partners to further develop 3D models.
- Identify the role and synergistic effects of growth factors and cytokines
- Oxidative metabolism and myofiber size are inversely related and hypetrophy and mitochondrial biosynthesis are mutually exclusive. We investigate the role of oxygen diffusion on the anabolic potential of myofibers and how oxygen supply can be improved by angiogenesis
- The extracellular matrix is a scaffold for myofibers which binds and sequester growth factors and cytokines but also plays a role in myofascial force transmission. Effects of tensile stress, shear forces and pressure are tested for their effects on protein synthesis in both radial and longitudinal myofiber direction.
- Muscle regeneration relies on the adequate activation and differentiation of muscle stem cells. We have recently shown that mechanical loading of these cells in their native niche on top of their host myofiber are sensitive to shear loading triggering their proliferation.

Model: brain‐on‐chip model
The CNRN is an expertise center at the Vrije Universiteit Amsterdam with over 150 researchers and 20 research teams. The CNCR has the mission to understand the mechanisms underlying brain function and dysfunction, providing new perspectives on diagnosis and treatment of brain diseases. The human iPSC technologies are increasingly implemented in the different CNCR research programs. The brain‐ on‐chip models are benefiting from CNCR’s leading experts in brain research from molecular to functional analysis, thereby validating, optimizing and making these systems more physiological relevant.

Researcher: Prof. dr. Bas Teusink
Develop and apply a systems biology workflow to design cell culture media that are fully chemically defined, truly animal‐free (no foetal calf serum) and are tailored to their purpose (fit‐for‐purpose)
In the field of microbiology, advances in bioinformatics and systems biology have made systematic and rational design of chemically defined media possible. It is based on the integration of omics data into so‐called genome‐scale metabolic models that simulate growth on the basis of nutrient inputs
and biomass requirements.
Development of defined and fit‐for purpose culture media can provide huge benefits:
No cross immunology
Chemically defined media for good manufacturing practice (GMP) and down‐stream processing
Control over nutritional, hormonal and growth factor needs and metabolic status
Unique data collection for insight in role of growth medium composition on cell physiology
