The invention is in the field of cell biology and immunology. The invention provides methods for the production of a vaccine for cancer and infectious diseases. More in particular it provides a method for the improved production of mature dendritic cells. This improved production includes the use of a bacterial lysate produced by a new method.

Provided is a method for the selective differentiation into M1 macrophages under a pressurized environment, and more particularly, a method for the selective differentiation of undifferentiated macrophages into M1 macrophages, the method including incubating the undifferentiated macrophages in an incubator under the pressurized environment. In addition, provided is a method for producing osteoclasts, the method including: incubating undifferentiated macrophages in an incubator under a pressurized environment to differentiate into M1 macrophages; and differentiating the differentiated M1 macrophages into osteoclasts.

Compositions and methods are provided for converting the predominant circulating classical monocytes to a non-classical and/or intermediate monocyte phenotype through cytokine stimulation via, for example, macrophage colony-stimulating factor. Once cultured into dendritic cells, these non-classical and/or intermediate monocyte derived cells have increased costimulatory molecule expression, which leads to improved immune and clinical responses in cancer patients receiving dendritic cell vaccination and other immunotherapies. In addition, assays and diagnostic and theranostic methods are provided herein that relate to the discoveries that, prior to treatment, intermediate (CD14+CD16+) and non-classical (CD14dimCD16+) monocytes are increased more than two-fold in patients who later had complete responses to dendritic cell therapy or DC vaccination.

A conditioned medium of CD11b.sup.low macrophages and methods for preparing it are provided. Pharmaceutical compositions comprising the CD11b.sup.low macrophages conditioned medium or a culture of CD11b.sup.low macrophages and their use in the treatment of cancer or fibrosis are also provided.

Compositions and methods for the treatment of leukodystrophy, particularly, H-ABC are disclosed.

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.

The present disclosure relates to a method for preparing NK cells and an application thereof in treatment of a cancer. The present disclosure provides a pharmaceutical composition prepared from NK cells and a monoclonal antibody of CD105, which can be used for the treatment of colorectal cancer and has a good application prospect.

Disclosed are means, methods, and compositions of matter for prophylaxis and/or treatment of SARS-CoV-2 by administration of dendritic cells in a manner and frequency sufficient to induce activation of innate and/or adaptive immune responses. In one embodiment the invention teaches administration of dendritic cells pulsed with one or more innate immune stimulants in a manner endowing said dendritic cell with ability to induce augmentation of natural killer (NK) cell number and/or activity. In another embodiment the invention teaches the use of dendritic cells stimulated with innate immune activators in a manner to allow for uptake of viral particles and presentation of viral epitopes to T cells in order to stimulate immunological activation and/or memory responses.

The invention relates to pharmaceutical compositions that contain COVID-19 peptide specific cytotoxic T cells, and to methods for treating or preventing COVID-19 infection.

A method for obtaining a composition for tissue regeneration, providing M2-macrophages, co-culturing the M2-macrophages with tissue-specific cells in serum free medium; and collecting the supernatant of the co-culture. The compositions obtained by this method are suitable in medicine regenerative treatments, able to regenerate injured tissue. These products are sterile cell-free physiological aqueous solutions that show specific tissue concentration patterns to provide optimal tissue-specific regenerative effects. The compositions may be stored for long periods cryopreserved or lyophilized until its use, avoiding any subsequent blood extraction from the cell-donor, the stored growth factors and/or cytokines biologically active after long-term storage. Moreover, the compositions may be potentially applied in both autologous and allogenic treatments.
