Previously useless fish scales can help heal open wounds

Until now, people have not thought about how fish scales can be used. However, according to scientists at the Nanyang Technological University (Singapore), scales can be of great help in the treatment of various wounds.

As samples, the researchers used collagen extracted from the scales of sea bass, snakehead and tilapia, which are bred in a Singapore fish nursery. After proper treatment, collagen was applied to the skin of the mice, and it was able to accelerate the formation of blood vessels and lymph nodes in it, which speaks in favor of effective tissue regeneration.

Previously, collagens obtained from the skins of cows, sheep and pigs have already been used in wound healing dressings, which, according to scientists, had significant drawbacks. Fish scales, as a source of collagen, are much cheaper, if only because they are waste that is usually thrown away. In addition, it turned out to be more effective.

In a previous study, researchers found that fish scale collagens injected into a person's umbilical vein increased the number of endothelial cells (cells that form the inner lining of blood vessels, lymph vessels, and heart cavities) 2.5 times more effectively than bovine collagen.
