BACKGROUND AND PURPOSE Coil embolization is safe and effective but may be followed by aneurysm recurrence. Our purpose was to explore the use of alginate as a new embolic agent that could deliver growth factors and improve results of endovascular treatment of aneurysms. METHODS We first assessed the potential of alginate as a vector for growth factor delivery by using in vitro binding and elu...

In vitro meat has recently emerged as a new concept in food biotechnology. Methods to produce in vitro meat generally involve the growth of muscle cells that are cultured on scaffolds using bioreactors. Suitable scaffold design and manufacture are critical to downstream culture and meat production. Most current scaffolds are based on mammalian-derived biomaterials, the use of which is counter t...

Objective: This study was aimed to determine the biocompatibility of gelatin-alginate scaffolds with 3D bio-printer and the mice bone marrow mesenchymal stem cells (BMSCs), and the histocompatibility during skin wound healing. Methods: BMSCs was separated and cultured using pan-marrow attachment method and the third generation combined with gelatin-alginate was added to the 3D printer for the p...

3D printing has emerged as one of the modern tissue engineering techniques that could potentially form scaffolds (with or without cells), which is useful in treating cardiovascular diseases. This technology has attracted extensive attention due to its possibility of curing disease in tissue engineering and organ regeneration. In this paper, we have developed a novel rotary forming device, prepa...

Sodium alginate (SA) and gelatine (G) based hydrogels for biomedical applications, such as wound dressing, were crosslinked by calcium chloride (CaCl2) or glutaraldehyde (GTA) in order to overcome their exudates solubility. Swelling behaviour of prepared hydrogels in phosphate buffered saline with different pH value at 37 ° C was compared. It was proved that the crosslinking agent concentration...

Heart valve disease is a serious and growing public health problem for which prosthetic replacement is most commonly indicated. Current prosthetic devices are inadequate for younger adults and growing children. Tissue engineered living aortic valve conduits have potential for remodeling, regeneration, and growth, but fabricating natural anatomical complexity with cellular heterogeneity remain c...

Highly porous 45S5 Bioglass(®)-based scaffolds coated with two polymer layers were fabricated to serve as a multifunctional device with controlled drug release capability for bone regeneration applications. An interior poly(d,l-lactide)/poly(ethylene glycol)-(polypropylene glycol)-poly(ethylene glycol) triblock copolymer (Pluronic P123) coating improved the mechanical stability of Bioglass-base...
