Collagen: What Are the Benefits and Side Effects?

Our muscle models behave in ways that closely reflect normal human muscle biology, and we’ve established multiple validation points to demonstrate this. We have validated them using compounds such as leucine, insulin, testosterone, and Resolvin E1, demonstrating predictable changes in muscle morphology and function. The tissues can also be mechanically or electrically stimulated to simulate exercise, thereby altering force production and muscle characteristics. We have developed disease models of metabolic disorders by exposing tissues to excess fatty acids, creating metabolic dysfunction similar to that observed under high-fat diet conditions. We can also induce injury using compounds such as barium chloride and observe subsequent regeneration, enabling detailed investigation of repair mechanisms in a highly controlled environment.

In nature, collagen is found exclusively in animals, especially in the flesh and connective tissues of mammals. Collagen is a part of the connective tissue that in the skin helps in firmness, suppleness and constant renewal of skin cells. Collagen is vital for skin elasticity. Ligaments are another type of connective tissue that attach two bones and consequently hold the joints together. Tendons are similar but different type of tissue that attach the muscles to the bones. All of these tissues, the bones, ligaments, tendons and the skeletal muscles themselves, are made up of proteins. One of the most predominant proteins is called collagen. Collagen is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content.

A Japanese firm, Amino Up Co., Ltd., produces a standardized extract of the mycelia of the cultured mushroom Lentinula edodes. AHCC has shown the ability to increase dendritic cell numbers in the blood, enhance virus elimination, increase influenza antibody titers post-vaccination, and reduce cancer recurrences after liver tumor resection. In the last case, its use was also associated with a reduction in cirrhosis odds compared to the group that did not take this agent. This prompted the current study, where AHCC was examined for its potential to prevent the progression of liver fibrosis by inhibiting hepatic stellate cell (HSC) activation.
