Résumé : |
One of the main effects of ageing on skin is the reduction on its ability to selfregenerate and create new extracellular matrix (ECM). This has an impact on the production of key structural proteins, such as collagen, but also on proteoglicans, which play a role on cellular signalling.
This paper presents the results on the activity of a combination of synthetic peptides whose structures have been specifically designed to reorganise into the skin to build up a three-dimensional polymeric net that is completely biocompatible. This net not only provides a structural support to the skin helping the anchoring of cells, but also activates cellular regeneration processes. Moreover, it is able to activate intracellular signals that stimulate the proliferation and differentiation of skin cells, activating synthesis of extracellular proteins. Therefore, this specific combination of peptides constitutes the scaffold to create a structure that behaves like the extracellular matrix itself. |
