Description

TECHNICAL FIELD The present invention relates to a composition for wound healing and skin regeneration comprising a seaweed extract,

The present invention relates to compositions for wound healing and skin regeneration comprising algae extract.

The skin occupies most of the human body and has various functions such as body temperature control, secretion, excretion, absorption, and especially functions to protect the human body physically, chemically and biologically from outside by being present at the outermost part of the human body. The skin is composed of epidermis, dermis and subcutaneous fat. The epidermis protects from the outside and inside of the body. The dermis has the function of supporting elasticity and support of skin, and subcutaneous fat has the function of maintaining body temperature.

Skin wounds usually indicate a state of damage to the epidermis and lower dermis layers that make up the skin. The normal course of wound healing is through the stages of hemostasis (clot formation), inflammation, proliferation (re-epithelialization, angiogenesis, fiber proliferation), and wound contraction. The hemostasis phase is the stage in which hematocrit is formed by red blood cells, white blood cells, platelets present in the blood vessels due to the rupture of the capillary vessels on the upper surface of the damaged window, and the immune cells such as white blood cells and neutrophils start to move to the wound sites And various cytokines are secreted. The inflammation stage is the stage of body protection that causes immune reaction with immune cells such as leukocyte, neutrophil, etc. that have been transferred to the wound area and substances such as foreign substances and pathogens entering from outside the wound, and treatment of damaged tissues occurs. The proliferative phase is the stage where fibroblast migration and proliferation occurs and tissue proteins such as collagen and elastin are produced and new blood vessels multiply into damaged tissue. Finally, the contractile phase is the step of tightening the loose coupling between the newly synthesized tissue and the proliferated cells, thereby increasing the joint strength and resilience of the tissue. In wound healing, rapid regeneration and restoration of the skin should be performed, and the proliferation phase must be performed promptly. In wound healing, fibroblasts migrate to the wound area, contracting the growth and wound area, and playing an important role in synthesizing extracellular matrix such as collagen.

Currently, EGF (epidermal growth factor), which is widely used as a wound healing agent because of its various activities, is either obtained by purification or obtained by overexpression in bacteria. It takes a lot of time, money, and labor to obtain by direct purification. Also, the over-expression method in bacteria has a problem that the recovery yield is very low due to low amount of cells in the cell and protease of bacteria. In addition, there is a report that EGF has a low therapeutic effect on a chronic wound site, and there is a problem that the price is higher than the efficiency due to a short half-life due to temperature and protease, so development of a new wound treatment agent is urgent.
