Abstract: Provided are methods of isolating and culturing various cells in a living state including peripheral blood mononuclear cells (PBMCs) isolated from peripheral blood, which use a cell membrane permeabilization method. The methods use a streptococcal hemolytic exotoxin, which binds to cholesterol present in a cell membrane so as to make a pore therein, thereby allowing an exogenous protein to be permeated into the cell, and is a technique of isolating and culturing desired cells in a living state by probing a specific intracellular protein and performing flow cytometry (FACS). According to the methods, various intracellular proteins that could not previously be isolated and cultured from a patient’s blood as well as various tissues may be targeted, and homogeneous cells may be obtained with high purity and high efficiency.

Abstract: Disclosed are a method for preparing induced pluripotent stem cells from endocardium-derived adult stem cells isolated from peripheral blood and a method for differentiating induced pluripotent stem cells into cardiovascular cells. The endocardium-derived adult stem cells are primary culture cells for preparing induced pluripotent stem cells, can be readily isolated and cultured only with a small amount of peripheral blood, have a high proliferation property so as to be storable without generic variation, and can rapidly ensure a cell number so as to be usable in cell therapy. The endocardium-derived adult stem cells have sternness, thereby having high preparation efficiency, and are derived from the endocardium so as to have the epigenetic memory of cardiovascular cells, thereby having an advantage of being able to be differentiated, after preparing induced pluripotent stem cells, into cardiovascular cells such as endothelial cells, smooth muscle cells and cardiomyocytes with a high efficiency.

Abstract: The present disclosure relates to endocardium-derived adult stem cells obtained by culturing peripheral blood mononuclear cells (PBMCs) separated from peripheral blood, and a cell therapeutic agent for treating cardiovascular diseases containing the same as an active ingredient. The adult stem cells have an origin that is the endocardium and strong blood vessel formation, and is thus remarkably useful for treating cardiovascular diseases such as ischemia, myocardial infarction, and the like.

Abstract: The present invention relates to a secondary battery. The secondary battery includes an electrode assembly built in a can, a positive electrode tab of the electrode assembly connected to a cap coupled to an upper end of the can, wherein the positive electrode tab having at least one bent portion, a negative electrode tab, and a buffer member inserted into the bent portion of the positive electrode tab. Thus, excessive bending of the positive electrode tab is prevented by the buffer member.
