Problems solved by technology

However, increasing a certain matrix component secreted by cells at a single level cannot maintain the balance of the extracellular matrix and improve the state of the extracellular matrix. There is no in-depth study on how to increase the secretion of ECM complex components at the same time.

Abstract

The invention discloses a preparation for promoting fibroblasts to secrete extracellular matrix components, and a preparation method and application thereof. The preparation comprises the components of A) the egg white of eggs, B) egg white lysozyme, and C) pyruvic acid or pyruvate, can also comprise ovotransferrin and / or glucose, and is obtained by mixing the components uniformly. The preparation can serve as an externally used paste for skin in application, and can obviously stimulate the secretion of collagen and hyaluronic acid synthase in the fibroblasts of the skin and improve the resiliency and the moisture content of the skin. The preparation is derived from a biologic extractive technique, has no harmful substance residues, safe and high-efficiency use, and is different from the prior method for promoting the secretion of a single fibroblast ECM component; besides, the preparation has multiple effects, wide application range and extensive application prospect, and can be applied in the fields of the preparation of skin substitutes, the preparation of anti-aging skin care products, cosmetics, medical treatment and the like.

Description

technical field [0001] The invention relates to a preparation for promoting fibroblasts to secrete extracellular matrix components, a preparation method and application thereof. Background technique [0002] The extracellular matrix (ECM), including collagen, noncollagenous glycoproteins, aminoglycans and proteoglycans, and elastin, maintains tissue function by maintaining cell survival, determining cell shape, regulating cell proliferation, controlling cell differentiation, and participating in cell migration Normal, maintain a strong metabolism, so as to maintain the youthful state of the body. Fibroblasts are involved in the secretion of various extracellular matrix components, including the regulation of the secretion of collagen, fibronectin, hyaluronic acid, chondroitin sulfate, dermatan sulfate, and elastin. [0003] Fibroblasts are also the main cell components in the skin dermis. The collagen fibers, elastic fibers and matrix components they secrete together with ...
