<pre>Before useless fish scales help to heal open wounds

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

As examples, the researchers used collagen extracted from the scales of sea bass, snakehead and tilapia, which are bred in the Singapore fish nursery. After proper treatment, the collagen was applied to the skin of 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 derived from skins of cows, sheep and pigs were already used in wound healing dressings, which, according to scientists, had significant shortcomings. Fish scales, as a source of collagen, are much cheaper, if only because it represents wastes that are usually thrown away. In addition, as it turned out, it is more effective.

In a previous study, scientists determined that collagen from fish scales introduced into the human umbilical vein contributed to an increase in the number of endothelial cells (cells forming the inner surface of the blood vessels, lymph vessels and cardiac cavities) 2.5 times more efficiently than when used cow collagen.
