Abstract: The invention relates to a method for separating blood, to a separation container and to a system, wherein different blood fractions—erythrocytes (64), buffy coat (65) and blood plasma (66)—are obtained, wherein blood is introduced into a separation container (1) and is then centrifuged into different superimposed, fluidically connected sections of the separation container, specifically a top section (4) for receiving the blood plasma (66), a middle section (3) for receiving the buffy coat, and a bottom section (2) for receiving the erythrocytes (64). The aim of the invention is to optimize the extraction of buffy coat. Said aim is achieved by means of the method and the separation container, wherein the optimization is geared to obtaining a defined phase boundary, and by means of the system, wherein the optimization is geared to achieving freedom from contamination from the time the blood enters the separation container and obtaining an easy-to-handle freezer container for cryopreservation.
Abstract: The present disclosure relates to methods for producing dopaminergic cells and evaluating their functionality. When pluripotent human embryonic stem cells are cultured on plates coated with laminin-111, laminin-121, laminin-521, laminin-421, or laminin-511 in cell culture medium containing a GSK3 inhibitor and a TGF-? inhibitor as well as timely administered fibroblast growth factor, desired neural cells are produced at far higher rates. Useful cell culture kits for producing such dopaminergic cells are also described herein, as are methods of using such cells for stem cell therapy.
Abstract: The present invention provides a method for testing an allergy capable of rapidly and highly accurately testing an allergic reaction. The method can determine whether or not a patient has an allergy or whether or not an agent that may be allergenic to a patient has an allergenicity (an allergic reactivity) in the patient. The method may comprise the steps of causing migration of leukocytes separated from a healthy human or cells of an established cell line with a chemotactic factor contained in a sample such as body fluid or blood of the patient to be tested or a sample stimulated with the agent that may be allergenic to the patient and analyzing the cell kinetics such as migration velocity, migration distance, and migration direction.

In addition, the medical fluid further includes albumin in a concentration not exceeding 5.0%, and an oxygen carrier, such as erythrocytes. Further components may be dopamine; hydrocortisone; methylprednisolone; and a vasopressor agent, such as desmopressin. The cocaine; adrenaline; and noradrenaline are present in concentrations of each about 0.010 ?M to 0.100 ?M, for example in a ratio of 1:1:1.

Abstract: A mammalian cell suspension prevents pulmonary embolism formation during administration of mammalian cells, such as mammalian stem cells, through a blood vessel, and a preventive agent against pulmonary embolism formation during administration of mammalian cells through a blood vessel. suspending mammalian cells, such as mammalian stem cells, are suspended in a physiological aqueous solution containing trehalose or its derivative, or a salt thereof as an active ingredient to prepare a mammalian cell suspension for preventing pulmonary embolism formation during administration of the mammalian cells through a blood vessel, including the mammalian cells and trehalose or its derivative, or a salt thereof as active ingredients. Examples of the mammalian cells can include pancreatic islet cells, dendritic cells, natural killer cells, alpha/beta T cells, gamma/delta T cells, and cytotoxic T lymphocytes in addition to mammalian stem cells.
Abstract: A purified human cell population of subsets of angiohematopoietic progenitor cells, wherein the population is at least 94% pure and wherein the cells are selected with cell markers selected from the group of KDR, APLNR, VE-cadherin, PDGFR?, CD31, CD235a, CD73, CD43, and CD41a.

Abstract: A method of treating a disease selected from the group consisting of emphysema, sepsis, septic shock, ischemic injury, cerebral ischemia, a neurodegenerative disorder, meningitis, encephalitis, hemorrhage, cerebral ischemia, heart ischemia and a cognitive deficit in a subject in need thereof is provided. The method comprising administering to the subject a therapeutically effective amount of a combination of at least two agents, wherein a first of said two agents upregulates an activity and/or expression of Nrf2 and a second of said two agents is a glutamatergic modulator, thereby treating the disease.
Abstract: The present invention provides a method for producing adult oligodendrocyte progenitor cells from proliferative oligodendrocyte progenitor cells, and a pharmaceutical composition having for an active ingredient thereof adult OPC produced according to that method. The method for producing adult OPC of the present invention is characterized by inducing proliferating OPC to differentiate into adult OPC by culturing in the presence of a ligand of a thyroid hormone receptor or retinoic acid receptor in a low oxygen environment. The present invention further provides adult OPC produced according to the production method of the present invention, and a pharmaceutical composition having these adult OPC as an active ingredient thereof.
Abstract: An apparatus and method to maintain pH within a range conducive for cell growth in a bicarbonate-containing cell culture system without the addition of base. The method relies on the gas transfer characteristics of the bioreactor system to modulate the CO2 transfer to and from the cell culture such that the pH of the cell culture can be maintained within a desired range.
