00 INTRODUCTION Gelatin hydrogels have attracted significant attention in the field of regenerative medicine, and more specifically, in their use as wound dressings and artificial tissue replacements. Among the different photo-crosslinkable gelatin materials, gelatin methacryloyl (GelMA) hydrogels display a series of advantages, such as good biocompatibility (including biosafety and biological […]
00 INTRODUCTION Working in sterile conditions is key for culturing our scaffolds in aseptic conditions and avoiding contamination. In a 3D Bioprinting protocol we have many sources of contamination, the biomaterial, the cells itself or the 3D bioprinting protocol. The scaffolds with or without cells have the same requirements in […]
+30 INTRODUCTION Type I collagen is the most abundant type of collagen in the human body, as a major structural matrix protein in skin and many other tissues including bone, tendon and fibrous connective tissues. ColBioink is a sterile solution of highly purified collagen type I from porcine origin that […]
+10 INTRODUCTION Collagen is the most abundant structural protein in the extracellular matrix (ECM), accounting for 30% of the total body protein content in humans. Amongst the 28 types of collagen that have been already identified, collagen type I is the most abundant by far, playing its most prominent functional […]
+10 INTRODUCTION Alginate is a FDA-approved natural polysaccharide extracted from brown algae with multiple applications in the food, cosmetic, and pharmaceutical industries. Its outstanding features including high biocompatibility, ease of gelation, tailorable rheological properties and degradation kinetics make it ideal for 3D bioprinting applications. Alginate hydrogels can be ionically crosslinked […]
+20 Introduction Electrically conductive thermoplastic elastomers hold idyllic attributes for the 3D printing of flexible and electroconductive scaffolds with applications in electronics, electromagnetics and computer industries. Beyond these applications, they have a tremendous potential in the biomedical sector. Due to their enhanced biocompatibility, they can be used as biosensors and […]
+20 Facilan™ PCL 100 Filament (MW = 50000 g/mol) was used as 3D printing filament. The scaffolds were designed with the software Regemat3D Designer v1.4.4 and printed using a Regemat3D Bio V1® bioprinter (REG4Life, REGEMAT 3D, Granada, Spain) equipped with a glass bed and a 0.4 mm diameter nozzle. The […]
+40 Introduction Hypoxia is a common characteristic of many solid tumors that has been associated with tumor aggressiveness. Limited diffusion of oxygen generates a gradient of oxygen availability from the blood vessel to the interstitial space and may underlie the recruitment of macrophages fostering cancer progression. However, the available data […]
+70 Introduction Choosing appropriate biomaterials for fabricating a bioink is a fundamental step in3D bioprinting. While a wide variety of biomaterials can be used, hydrogels have been pointed as attractive materials for bioink preparation, since they can provide a highly hydrated and permeable 3D polymeric structure with tunable mechanical and […]
