Title: Composition for tissue regeneration and wound healing comprising induced exosomes
Inventor: LEE YONG SEUNG
IPC: C12N13/00
Filed: 2018-10-02
Abstract: Disclosed is a method of preparing exosomes having skin regenerative and wound healing effects. The method comprises the steps of: providing ultrasonic stimulation to cells and providing ultrasonic stimulation to a cell-free culture medium; mixing the cells with the culture medium, and culturing the same for a predetermined time; and isolating exosomes from the mixture, wherein the culture medium is any one among a vascular endothelial progenitor cell culture, a mesenchymal progenitor cell culture, an epithelial stem cell culture, a dermal stem cells culture, a hematopoietic stem cell culture, an adipose stem cell culture, a mesenchymal stem cell culture, and an embryonic stem cell culture. The method of preparing exosomes can obtain, through a simple process of ultrasonic treatment, exosomes having skin regenerative and wound healing effects at a high yield over a short time, not only from stem cells which are difficult to handle, but also from somatic cells easily acquired and maintained. The exosomes thus acquired contain a large amount and number of various factors, and moreover, the exosomes and a composition comprising the same show an increase of various factors capable of inducing skin regeneration and wound healing. Since the exosomes have a phospholipid-based membrane structure, and thus can easily penetrate the skin and provide a high substance delivery efficiency, the exosomes can effectively induce skin regeneration and wound healing, and have an advantage in that the exosomes are safe and show no adverse side effects seen from the use of synthetic drugs.
