Created substances capable of tissue regeneration start

Restorative the ability of our body is very high. However, this is true only if we are talking about minor injuries. The same deep cuts after healing often do not overgrow the normal skin and coarse scar tissue. Scientists around the world are regularly looking for ways to improve the regenerative capacity of the human body (the more so because such examples in the animal world is full). And it is possible that a group of researchers from Canada have succeeded. If you are interested in this topic, be sure to subscribe to our news feed Telegram.

How to run a process of tissue regeneration

Surprisingly, its outdoor swimming scientists have made in the course of work on the study of antibodies that the body produces to fight infections. This is not the first case in the world practice, when antibodies are "converted" to drugs. This is due to their ability to bind to proteins and influence in such a way to work the living cells. Since proteins encoded by a specific set of genes, they can be easily created in the laboratory using genomic technology and protein engineering. As the researchers report, they were able to develop their "improved synthetic analogs" based on antibodies.

We are in their studies using antibodies, creating new molecules that do not exist in nature. But the subject is not less than their potential is huge - said one of the authors, Professor of the Center for Cellular and Biomolecular Research Donnelly, Sahdev Sidhu. Using available methods, we can create a substance that will transform the entire regenerative medicine. And at the same time to produce them will not be so expensive.

New substances are called FLAG. They are inherently analogues Wnt proteins. The fact that the body of Wnt proteins trigger the process of growth and development of stem cells into cells of any other kind. Wnt very active during the formation of the embryo, but after the birth of the activity of these proteins is reduced. But why then just do not "add" Wnt? Why create analogs?

In fact, the Wnt in an adult organism is still present in small amounts, and even performs its function. Only now, this protein is so "strong" that can cause uncontrolled cell growth, which will lead to the development of cancer. Therefore, it wants to create a substance that would perform the same function, but whose work could be easily adjusted. And there was a FLAG.

People for decades have tried to "straighten" the Wnt proteins and make them into drugs. The problem is that these proteins are arranged in such a way that they are difficult to manage. Furthermore, lipids in the composition to prevent the dissolution of Wnt proteins in water, which makes them unsuitable as drugs.

Naturally, scientists have conducted a series of experiments. When FLAg added to cell culture, they behaved in precisely the same way as Wnt, stimulating cell growth. Thanks to a "fine-tuning" managed to stimulate the formation of stem cells derived from tissue balls that resemble small intestine.

This is interesting: A structure with extensive regenerative potential than stem cells.

But that's not all. When administered in the digestive tract FLAg laboratory mice, animals active intestinal stem cells, with one side showing that stable and functional antibodies within the organism, and on the other that the simple introduction of enough to start the regeneration process. At the same time, scientists are assured that they can develop other specific embodiments FLAg for the regeneration of the lungs, liver, bones and other tissues of the body.
