CollPlant Biotechnologies announced that its recombinant human collagen (rhCollagen)-based bioink was used successfully by researchers from Israel'sTechnion Institute of Technology to create a 3D bioprinted implantable tissue containing a network of blood vessels capable of supplying blood to the implanted tissue. As the fundamental building block in human tissues, Type I collagen provides multiple biological signals, including mechanical and chemical signals mediating cell binding and interactions with other extracellular matrix molecules and growth factors. In contrast to previous studies where collagen from animals has been used to form scaffolds, the researchers at the Technion used CollPlant's rhcollagen-based BioInk owing to its unique physical properties, outstanding biological functionality and excellent compatibility with photopolymerization 3D printing.
