What are fibroblasts?
Fibroblasts are the most common cells of connective tissue, housed in skin, tendons and other tissues. Connective tissue is responsible for some functions of padding, support, elasticity and protection.
They are located in the dermis, the middle layer of the skin, and also in the hypodermis, the deepest layer of the skin. They can also be found in other types of connective tissue, such as bone tissue, muscle tissue, nerve tissue and connective tissue.
Function of fibroblasts
- The function of fibroblasts is to secrete collagen proteins to maintain the structure of many tissues.
- They are also involved in wound healing. When a wound occurs, fibroblasts are activated to participate in the production of extracellular matrix and repair damaged tissues.
- Fibroblasts secure connective tissues by giving them support, strength and elasticity. But it has been proven that after the age of 40, the body loses approximately 1% of collagen per year.
- Fibroblasts can also release cytokines and other inflammatory mediators to help regulate inflammation in the body.
Over the years, like other cells, fibroblasts lose their capacity, in this case to produce collagen and other substances. This involves changes in the texture, luminosity and tone of the skin, which accentuates the signs of aging.
