Sichuan Rivotek Co has printed 3D blood vessels with stem cell-based bio-ink. Blood vessels are ubiquitous in all living organisms; their creation, via bio-ink and 3D printing could portend widespread application across all fields of regenerative medicine. As 3D printing progresses, more patient specific parts and even organ systems may be developed. Earlier modes of 3D printing that have used titanium instead of bio-inks have created surgically implanted jawbones and rib cages in experimental settings, providing valuable information to guide future development.
As part of ongoing research in organ system regeneration, the development of 3D printing represents a rapidly growing field of technology. The creation and application of tissue-based inks has been a conundrum for researchers. The development of mesenchymal stem cell based ink permits the manipulation of actual tissue, not inorganic materials like titanium. As scientists master the complexities and limitations of 3D printing, additional stem cell-based, bio-ink 3D printing applications will emerge.
