20110142809 | METHOD FOR SEPARATING HIGHLY ACTIVE STEM CELLS FROM HUMAN STEM CELLS AND HIGHLY ACTIVE STEM CELLS SEPARATED THEREBY - 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. | 06-16-2011 |
20110256626 | METHOD FOR PRODUCING INDUCED PLURIPOTENT STEM CELLS WITH HIGH EFFICIENCY AND INDUCED POLURIPOTENT STEM CELLS PROUCED THEREBY - The present invention provides a method for producing customized pluripotent stem cells. Specifically, the present invention comprises following steps: extracting proteins from any of the dedifferentiated stem cells or induced pluripotent stem cells, the said dedifferentiated or pluripotent stem cells being prepared by any known method; introducing the protein extract into the adult somatic cells; and culturing the adult somatic cells to produce pluripotent stem cells having the same pluripotency as that of embryonic stem cells. In addition, pluripotent stem cells produced according to the present method and cell therapeutics comprising the same are provided. The method allows pluripotent stem cells to be produced very easily and at a significantly higher yield, compared to typical methods. | 10-20-2011 |
20120276625 | METHOD FOR PRODUCING MESENCHYMAL STEM CELLS FROM HUMAN PLURIPOTENT STEM CELLS, AND MESENCHYMAL STEM CELLS PRODUCED BY SAME - Provided is a method for producing mesenchymal stem cells from human pluripotent stem cells, the method including: a) forming embryonic bodies from human pluripotent stem cells; b) attaching the embryonic bodies to a culture dish to induce natural differentiation of the embryonic bodies into mesenchymal stem cells; and c) performing continuous proliferative culturing of the mesenchymal stem cells while still maintaining the identity of the mesenchymal stem cells. Also, provided is a standardized method for inducing differentiation of mesenchymal stem cells, which can be broadly applied to all human pluripotent stem cells regardless of a difference in the genetic background thereof. Ultimately, the present invention can continuously mass-produces the mesenchymal stem cells necessary for regenerative medicine and cell therapy by using human pluripotent stem cells, thereby realizing practical uses of cell therapy products, and further the present invention is expected to highly contribute to treatments of incurable diseases, such as cardiovascular diseases and neurological disorders. | 11-01-2012 |
20130023048 | Method of Inducing High Activity of Human Adipose Stem Cell and Medium Therefor - The present invention relates to a method of inducing high activity of human adipose stem cells, highly active stem cells induced by the method, cell therapeutic agents including the highly active stem cells, and a medium for inducing high activity of human adipose stem cells. | 01-24-2013 |
20130028873 | METHOD FOR INCREASING ACTIVITY IN HUMAN STEM CELL - Provided are a method for preparing a highly active human mesenchymal stem cell, which includes forming a spherical cell aggregate by cultivating human mesenchymal stem cells against gravity; a highly active stem cell prepared thereby; a cell therapeutic agent including the stem cell aggregate; and a method for forming a spherical cell aggregate by cultivating human mesenchymal stem cells, wherein the amount of E-cadherin in the mesenchymal stem cell is increased during the cultivation. | 01-31-2013 |
20130164841 | METHOD FOR INDUCING HUMAN BLOOD-BORN HEMATOSPHERES THROUGH AGGREGATE CULTURE AND EXPANDING BLOOD ADULT STEM CELLS AND PROGENITOR CELLS, AND STEM CELL PREPARED BY THE SAME - 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. | 06-27-2013 |
20140011275 | COMPOSITION FOR SUSPENSION CULTURING OF STEM CELLS - The present invention relates to a composition for suppressing the 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. | 01-09-2014 |
20140171489 | HUMAN RESISTIN RECEPTOR AND USE THEREOF - The present invention concerns a human resistin receptor. More particularly, the present invention provides a method for screening a receptor of human resistin protein, a method for preventing or treating an inflammatory disease and arteriosclerosis using an expression- or activity-regulator for a human resistin receptor, and a pharmaceutical composition including an expression- or activity-regulator for the human resistin receptor. The method for screening a human resistin protein receptor according to the present invention enables separation of a receptor which directly binds to resistin from human monocyte, reveals a mechanism of signal transduction of the resistin receptor, and therefore, is expected to contribute to regulation of an inflammatory effect of monocyte, molecular detection of causes for vascular inflammation and arteriosclerosis, and developments of prevention and a treating agent for an inflammatory disease and arteriosclerosis. | 06-19-2014 |
