Extensive scientific work was carried out under the direction of Salvador Aznar Benitah..

A group of scientists studied and compared the skin of mice of different ages using RNA sequencing, microscopes and DNA microarrays..

As a result, experts managed to understand the cause of aging of the skin, which is that the skin in the elderly loses its elasticity and strength due to changes in fibroblatts and collagens.. As a result of the loss of elasticity and strength of the skin, the elderly are at risk of contracting many diseases through the skin.

The work was published in the scientific journal "Cell".

Fibroblasts - cells of the connective tissue of the body, synthesizing extracellular matrix.

Fibroblasts secrete (secretion - the process of isolating chemical compounds from the cell) precursors of collagen and elastin proteins. In the process of aging, fibroblasts acquire some qualities of adipose tissue.. Thus, cellular identity is lost..

Collagen and elastin - two proteins that are responsible for the strength and elasticity of the fabric. Their secretion decreases due to changes in the quality of fibroblasts, and the skin ages..
