Scientists from the Krasnoyarsk Scientific Center of the SB RAS have developed special 3D frames that allow bone to heal even with very serious damage. In this respect reports “Reedus.” It is stated that the implant, which fulfills its function, is absorbed into the body and leaves behind complete bone tissue.
The scaffolds are made from naturally occurring hydroxy fatty acid derivatives synthesized by the bacterium Cupriavidus eutropus. Scientists obtained plastic “threads” from this polymer, placed them in a 3D printer and printed the implants.
The development was tested on the femur of a domestic pig. The experiment showed that the cells that form the bone tissue actively populated the surface of the frame, and after five months the bone damage disappeared without a trace. The polymer was absorbed into the body and split into butyric acid monomers.
It is emphasized that the development is suitable for both patients with fractures and people who have lost bone tissue due to tumor, infection or other factors.
In 2023, young scientists from NUST MISIS developed a biocompatible osteochondral implant prototype for the treatment of degenerative diseases of the knee joint. In this respect “socialbites.ca” the university press service reported.
Previously Swiss and American biologists started Regeneration of nerve cells in mice with spinal cord injury, partially restoring the animals’ ability to walk.
