Cartilage structures can be damaged causing two types of injuries: focal; the lesion is restricted to a concrete zone or diffuse; the lesion affects a broad area of the articular cartilage. This type of lesions appears due to the reduced self-healing capacity of articular cartilage. Diffuse damage is much more difficult to treat. As the damage progresses up to the point where the... -

When the healing process fails to proceed through the four physiological phases, the wound is referred to as a chronic wound1,2,4,5. Chronic wounds are a significant global... -

3D bioprinting is ideally positioned to promote the (vascular) complexity of in vitro engineered tissues. However, the resolution of extrusion-based printing, the most widespread bioprinting technique, is too limited to create microstructural features such as capillaries. Therefore, we have previously developed printable vascularized spheroids (Ø≈100-130 µm) by seeding human... -

As the global elderly population increases year by year, the demand for dental implants also increases significantly, Titanium (Ti) is widely used in dental implants due to its good mechanical properties, biocompatibility and corrosion resistance. However, titanium implant surfaces are biologically inert, it won’t react with cells actively and the implant may failed. The success of dental...

Bladder cancer is the 10th most common cancer worldwide. About 20% of bladder cancers are muscle-invasive and are indication for a radical cystectomy. The use of ileal segment is a standard method for urinary diversion after bladder removal. Use of this method extend surgical procedure and lead to numerous metabolic complications. To overcome these side effects, tissue... -

The generation of human induced pluripotent stem cell (hiPSC)-derived kidney organoids have facilitated novel insights into renal developmental processes and have the potential to provide personalised treatment strategies for patients with end-stage renal disease. Traditional protocols for the directed differentiation of hiPSC-derived kidney organoids have predominantly focused on biochemical...

Bone grafting is among the most frequent forms of transplantation, utilized to manage a variety of bone defect cases. Enriching synthetic bone substitutes with immune-interacting properties can be a strategy to improve their performance. The host’s response to e.g. microbial components can result in both a positive or negative effect on bone formation. As an immunomodulatory... -

3D inkjet printing provides a vital tool to deposit biomaterials with high precision (in the micrometer range) to address the complexity required for 3D scaffolds fabrication. However, its implementation is hindered by the lack of inks that exhibit properties optimal for tissue regeneration, and meet the properties for the demanding inkjet printing process. We address this... -

In vitro models of biological barriers (e.g., lung epithelium, intestinal epithelium) provide an important benchmark for studying the physiopathological processes (e.g., nutrient and metabolite exchange, interactions with external virus or bacteria) involved in the development of several diseases (e.g., respiratory tract infections, carcinomas). These models represent a reliable platform for a...

Anatomically-correct models of human skin are highly desired by both biomedical sciences and industry. Organotypic skin cultures, termed full-thickness skin equivalents, including fibroblasts and keratinocytes, thus forming dermis and epidermis are in use. However, a more detailed model of the skin is difficult to set up due to its cellular heterogeneity, complex vascular... -

For almost a century, in vitro 3D tissue models of skin are known. However, these 3D skin models are mainly used for basic cosmetic testing rather than for clinical application. This is because of a lack of reproducible methodology, physiological structures and tissue architecture. An essential step in the development of a physiologically relevant in-vitro skin model is the incorporation of...

Bioprinting is gaining an ever-increasing research interest thanks to its promising new applications in the field of tissue engineering. The main issue regarding this biofabrication technique is the engineering of suitable bioinks, accommodating both the requirements for fabrication and for cell culture and signalling. Versatile platform bioinks, with easily tailorable... -

Mesenchymal stem/stromal cells (MSC) have shown their regenerative potential in vitro, in preclinical models and are increasingly used in clinical applications as well. For cell therapeutic applications, MSC must be isolated from their resident tissues. For the isolation of MSC from adipose tissue, more and more systems are entering the medical device market. During the automated or semi...

"Introduction
Using nanofibrous materials for wound healing is very promising yet still challenging. The dressing is usually a composite made of several layers, with a specific role to ensure proper moisture of the wound, breathability, low adhesiveness to the wound and prevention of the infection. One of the benefits that nanofibers have is the ability to easily incorporate antimicrobial...

"Burned skin wound treatment is one of the most expensive burdens on healthcare systems worldwide. The severity and extension of burn trauma could elevate the rate of hospitalization, and patients with burn wounds are especially vulnerable to infections. Burn injuries are very challenging to manage since it causes loss of the integrity of large portions of the skin, leading to major disability...
