Porous bioceramic scaffolds based on akermanite obtained by 3D printing for bone tissue engineering

Ceramics International 2023 Volume 49, Issue 22, Pages 35898-35906

Porous bioceramic scaffolds were obtained by the 3D printing technique starting from a mixture of hydroxypropyl methyl cellulose and a powder obtained by sol-gel method which contains merwinite, monticellite, pseudowolastonie and periclase.The scaffolds were thermally treated at 1370 °C for 3 h and the main mineralogical compound assessed by XRD was akermanite. The obtained scaffolds have adequate mechanical and biological properties thus a great potential for applications in hard tissue engineering. The positive results obtained for this type of scaffolds are due to the precision of 3D printing technique, i.e. ability to control shape and size of both scaffolds and…

Alginate and Nanocellulose Dressings With Extract From Salmon Roe Reduce Inflammation and Accelerate Healing of Porcine Burn Wounds

Journal of Burn Care & Research 2023 Volume 44, Issue 5, Pages 1140-1149

Partial-thickness thermal burn wounds are characterized by a prolonged inflammatory response, oxidative stress, tissue damage, and secondary necrosis. An optimal dressing for burn wounds would reduce inflammation and oxidative stress while providing a moist, absorbent, and protective cover. We have developed an extract from unfertilized salmon roe containing components with potential anti-inflammatory and antioxidative properties, called HTX. HTX has been combined with alginate from brown algae and nanocellulose from tunicates, and 3D printed into a solid hydrogel wound dressing called Collex. Here, Collex was tested on partial thickness burn wounds in Göttingen minipigs compared to Jelonet, and a variant of…

Three-Dimensional Bio-Printed Cardiac Patch for Sustained Delivery of Extracellular Vesicles from the Interface

Gels 2022 Volume 8, Issue 12, Article 769

Cardiac tissue engineering has emerged as a promising strategy to treat infarcted cardiac tissues by replacing the injured region with an ex vivo fabricated functional cardiac patch. Nevertheless, integration of the transplanted patch with the host tissue is still a burden, limiting its clinical application. Here, a bi-functional, 3D bio-printed cardiac patch (CP) design is proposed, composed of a cell-laden compartment at its core and an extracellular vesicle (EV)-laden compartment at its shell for better integration of the CP with the host tissue. Alginate-based bioink solutions were developed for each compartment and characterized rheologically, examined for printability and their effect…
