The bone is a complex and dynamic tissue, in which the equilibrium between bone deposition and resorption can be perturbed by various pathological conditions, including bone metastases. Against them, no effective therapy has been developed yet, and available treatments are primarily palliative, aiming at restoring bone homeostasis. To improve the process of anti-metastatic drug discovery, new...
"Development of novel bone biomaterials inevitably has a phase of in vitro testing for cytocompatibility and functional osteogenesis. This relies on defined conditions under which osteoblasts, or their precursors, are stimulated to drive a mature, matrix depositing osteoblast phenotype. Based on the in vitro results obtained, a selection is made to be further tested using in vivo studies....
Introduction: Bone marrow is one of the most preferable sites for metastasis, but the complicated in vivo metastatic niches make it challenging to study cancer cell colonization. We took a novel approach to establish an in vitro complex bone marrow environment on a dynamic 3D culture system, Bone marrow (BM)-on-chip. With a specific focus on prostate cancer, we designed, fabricated, and...
Intro: Our broader understanding of the immune system's role in determining the success of intrinsic repair mechanisms has led to increased research focus on immunomodulatory therapies1. These therapies could be particularly effective in abnormal fracture healing, where bone tissue engineering has thus far failed to provide safe and reliable clinical therapeutics. While current developments...
Bone is a complex composite material, so any scaffold or model designed to reconstruct its integrity or model its behaviour must have a high degree of complexity and fulfil several requirements, including high biocompatibility, suitable surface and mechanical properties, adequate architecture, tailored degradability. Obtaining a bone-mimetic composition is also crucial, because hydroxyapatite...
A limitation, when it comes to 3D printed biomimetic structures with micrometer and sub-micrometer precision are computer aided design (CAD) programs. Existing CAD software is usually based on “manual” step-by-step design principles intended and suitable for subtractive and formative manufacturing methods rather than organic designs for additive manufacturing. The resulting structures can...
Cancer, as a cause of death, is only surpassed by cardiovascular diseases. Thus, it is critical to achieve progress in its treatment and prevention. Given the complexity and heterogeneity of cancer, various therapeutic targets are being investigated, including components of the tumor milieu. The tumor microenvironment (TME) consists of several types of cells (vascular cells, tumor-associated...
