Abstract:
The present invention relates to a composition for preventing or treating ischemic disease comprising endothelin or a nucleotide sequence encoding endothelin as an active ingredient, and more particularly to a composition for preventing or treating ischemic heart disease, myocardial infarction, angina pectoris, lower limb artery ischemia, distal limb ischemia and ischemic cerebrovascular disease, wherein the composition is administered by intramuscular injection. According to the present invention, administering endothelin-1 by intramuscular injection may efficiently inhibit the progress of ischemia, fibrosis and tissue necrosis, and induce angiogenesis, such that it is promising for preventing or treating the ischemic disease.
Abstract:
The present invention relates to a composition for suppressing cell death of stem cells during suspension culturing, a composition for mass culturing of stem cells, and a method for suppressing cell death of stem cells during suspension culturing. The composition of the present invention can be usefully used for effective single suspension culturing of stem cells, particularly, mesenchymal stem cells, or used for mass suspension culturing under the circumstances in which cell aggregation does not occur.
Abstract:
Disclosed is a method for increasing the activity of human stem cells. The method is characterized by treating a culture medium with endothelin-1. Also, the highly active human stem cells prepared by the method and cell therapeutics comprising the highly active human stem cells are provided. Human mesenchymal stem cells of various origins can be activated by the method, and thus resulting highly active human mesenchymal stem cells can be developed as effective cell therapeutics.
Abstract:
This invention is directed to the use of certain pharmaceutical compositions containing celecoxib for preventing and treating vascular restenosis. The pharmaceutical compounds including celecoxib of the present invention can significantly reduce neointimal hyperplasia through an inhibition of VSMC (vascular smooth muscle cell) proliferation and an increase in VSMC apoptosis. From these results, celecoxib can be used for preventing and treating artery restenosis.
Abstract:
The present invention relates to a method which makes use of either Ang1 (angiopoietin 1) or COMP-Ang1 (cartilage oligomeric matrix protein-angiopoietin 1), which regulate the differentiation mechanism of stem cells, so as to induce specific differentiation into muscle cells. Provided are a composition which is highly efficient in inducing differentiation from stem cells into muscle cells, and a therapeutic composition for diseases involving muscle damage using the differentiation-inducing ability. Consequently, the outstanding activity of the composition of the present invention can be used to advantage in the alleviation or treatment of diseases involving muscle damage such as muscular dystrophy, muscle inflammation and fibrosis.
Abstract:
The present invention relates to a human resistin receptor. More specifically, provided are a method for searching for a receptor for a human resistin protein, a method for preventing or treating inflammatory diseases and atherosclerosis using a regulator which regulates the expression or activity of a human resistin receptor, and a pharmaceutical composition containing a regulator which regulates the expression or activity of a human resistin receptor. It is possible to separate a receptor which directly binds to resistin from human monocytes using the method for searching for a receptor for a human resistin protein of the present invention, and the discovery of the signal delivery system of a resistin receptor is expected to contribute to the regulation of inflammatory effects of a monocyte, the diagnosis of the molecular cause of blood vessel inflammation and atherosclerosis, and the development of an agent for preventing and treating inflammatory diseases and atherosclerosis.
Abstract:
The present invention relates to a technique of using monocytic blood cells to effectively culture and proliferate blood adult stem cells and progenitor cells that only exist in small quantities to effectively obtain large quantities of stem cells. According to the present invention, the limitation of being able to derive only small quantities of stem cells from blood can be overcome, and the pluripotency of stem cells can easily be obtained.
Abstract:
The present invention relates to a pharmaceutical composition comprising a compound of formula (1), (2) or (3) as defined in the specification for the prevention or treatment of diseases associated with oxidative stress, mitochondria dysfunction, hypoxic injury, necrosis and/or ischemic reperfusion injury, and a cosmetic composition comprising an indole compound having an antioxidant effect.
Abstract:
The present invention relates to a composition for preventing or treating ischemic disease comprising endothelin or a nucleotide sequence encoding endothelin as an active ingredient, and more particularly to a composition for preventing or treating ischemic heart disease, myocardial infarction, angina pectoris, lower limb artery ischemia, distal limb ischemia and ischemic cerebrovascular disease, wherein the composition is administered by intramuscular injection. According to the present invention, administering endothelin-1 by intramuscular injection may efficiently inhibit the progress of ischemia, fibrosis and tissue necrosis, and induce angiogenesis, such that it is promising for preventing or treating the ischemic disease.
Abstract:
The present invention relates to a method for separating highly active stem cells from human stem cells, the highly active stem cells separated by the method, a cell therapeutic agent containing the stem cells, and a medium for separating the highly active stem cells from stem cells containing a specific cytokine. According to the present invention, the method is useful for separating the highly efficient stem cells from mesenchymal stem cells of various origins. Further, the method is very useful in developing a cell therapeutic agent of high efficiency because the method can be applicable to stem cells of various origins which are cultured under different conditions. Senescent stem cells increased by several passage times in vitro can be effectively sorted out, so the method can be used for reactivating the stem cells.
