A cellular patch capable of setting the heart rhythm has been developed at the Moscow Institute of Physics and Technology (MIPT). This was reported by the university's press service.
The size of the new biological "patch" is 1 sq. cm. The patch consists of polymer fibers and a monolayer. They perform the function of pacemakers (cells that control the heart rhythm).
Injections of stem cells or pacemaker cells into the heart lead to trauma and inflammation of tissues. The new development will eliminate negative consequences.
The patch was tested during heart surgery on a pig.
The implantation of the cellular patch itself took about half an hour - this is the time required for the formation of a primary connection between the animal's heart tissue and our patch. Then we conducted an experiment with illumination to "wake up" the pacemaker cells, and recorded a change in the heart rhythm of the pig.
In the future, scientists plan to study the activity of pacemaker cells and conduct additional operations.
Earlier www1.ru reported that a Russian soluble patch implant has been developed for the treatment of oncological diseases.
