A line of hydrogels and bio-inks for 3D bioprinting of cartilage and bone tissues, skin and mucous membranes has been developed at the Samara State Medical University (SamSMU). All materials were created in the Samara tissue bank of the Research Institute "BioTech" of the medical university using a patented technology.
Nikolai Ryabov, Senior Researcher and Head of the Bioprinting Laboratory of the Research Institute "BioTech", noted that the main feature of allogeneic biomaterials is their high biocompatibility. This minimizes the risk of rejection. The new materials differ from their xenogeneic (derived from animal tissues) and synthetic counterparts.
They provide ideal conditions for tissue regeneration, fully meeting the principles of reparative regeneration - the process of restoring cells, tissues and organs after injury and during various pathological processes.
The developed technologies can be applied in various fields of medicine. In traumatology, doctors will be able to restore complex fractures by filling bone defects with personalized bioprinted implants. In orthopedics, the technology will allow creating anatomically accurate cartilage structures for joints.
In dentistry, it will become possible to print bioactive membranes for guided tissue regeneration in the treatment of periodontitis or restoration of lost areas of bone tissue and mucous membranes. In ophthalmology, bio-inks will help grow corneal or conjunctival transplants for patients with burns and eye injuries, restoring their vision without the risk of an immune response.
Earlier www1.ru reported that the Russian crew on the ISS will test 4D bioprinting of tubular organs.
