The concept of rapid recovery of damaged body tissues has been developed.
Earlier it was hypothesized that the rapid recovery process may be promoted by the injection of biomaterials that would stimulate intact tissue cells to divide with the appearance of new cells. Special attention was paid to such a hypothetical possibility by military doctors, in whose interests - the rapid restoration of wounded soldiers and their subsequent return to service.
In Canada, engineers announced the creation of a special device for the so-called cell encapsulation.
A concept was created at the University of British Columbia at the Department of Engineering, which allows for the introduction of living cells into damaged tissue as a material so that they stimulate the regenerative processes in the body.
Associate Professor of the Department of Engineering K. Kim says that with the help of this concept it is possible to correct a variety of disorders in tissues, including bone. According to him, the approach allows you to quickly recover from a torn ligament, fracture, stab and other wounds.
The research results are published in the journal Lab on a Chip.
K.Kim:
The problem is that initially the cells injected into the damaged tissue were rejected by the body as alien to it. The immune system did everything so that they were not included in the work.
Scientists have developed the principle of the conclusion of living cells in a special shell before introducing them into the body. This is the encapsulation process. The function of the capsule for cells is performed by the so-called microgel, which protects the cells from being destroyed by the human immune system. Then, using laser technology, the cells are “cleaned” and begin to work.
Immunity to such cells reacts to a lesser extent, as they are already in the body.
According to the engineers, the technology allows you to save up to 85 percent of biomaterials artificially introduced into the fabric. The extent to which the recovery process is proceeding more actively when using this concept is not reported.
It is noted that one of the tasks is the encapsulation of stem cells.
