A method for the preparation and/or generation of immunomodulatory cells which comprises contacting a mesenchymal stem cell (MSC) and/or fibroblast cell population with peripheral blood leukocytes for between about 2 hours and about 25 days is described herein.

Provided is a method of preparing a three-dimensional cell spheroid, the method including forming the cell spheroid by co-culturing adipose-derived stem cells or mesenchymal stem cells with hepatocytes. According to the cell spheroid prepared by the method, the secretome secreted by the adipose-derived stem cells affects hepatocyte maturation, and therefore, hepatic functions of the finally formed three-dimensional cell spheroid, i.e., organoid, may be enhanced. Further, a composition including a culture medium of the adipose-derived stem cells may prevent or treat liver diseases including hepatitis, hepatotoxicity, cholestasis, fatty liver, etc., and may enhance hepatic functions.

Provided is a composition capable of promoting osteogenic differentiation of stem cells, comprising, as active ingredients, a bone and cartilage progenitor cell culture solution and a multilayer graphene film, which promotes the differentiation of stem cells into specific cells, and thus is expected to be variously applicable in the in vivo/in vitro stem cell application fields.

The present invention generally relates to a method for preparing induced mesenchymal stem cells (iMSCs) and its applications. The iMSCs, like MSCs, can differentiate into multiple lineages, which may be beneficial for disease treatments. In addition, the present invention also provides a method for improving the MSC's functional characteristics such that the MSCs are more suitable for cell therapy or in vitro applications.

Methods of inducing a polarization of macrophages. The method includes obtaining a blood fraction, fractionating the blood fraction to produce a blood fraction, and contacting the blood fraction with a source of macrophages. A blood fraction including platelet-poor plasma polarizes the source of macrophages into M1 macrophages. A blood faction including a protein solution polarizes the source of macrophages into M2 macrophages.

To provide a culture supernatant preparation which has excellent biocompatibility and contains a large quantity of specific genes or proteins. A method for producing the culture supernatant preparation including: a first culturing step of culturing cells to a confluent state using a first medium; a second culturing step of culturing the cells using a second medium that is different from the first medium after the first culturing step; and a culture supernatant preparation obtaining step of obtaining the culture supernatant preparation including the second medium after the second culturing step, the second medium including a calcium ion and a buffering agent.

Methods of producing stem cell conditioned media to treat mammalian injuries or insults. In at least one embodiment of a method of producing a stem cell conditioned media of the present disclosure, the method comprises the steps of culturing at least one stem cell in a first cell culture medium, replacing some or all of the first cell culture medium with a second cell culture medium and further culturing the at least one stem cell in the second cell culture medium, and collecting a quantity of the second cell culture medium after a culture duration, wherein the quantity of the second cell culture medium contains a cell culture byproduct effective to treat a mammalian insult or injury.

A method of preparing a functional trabecular meshwork (TM) cell from adipose-derived stem cells is provided. Methods of treating glaucoma, implanting trabecular meshwork (TM) cells, or repairing or regenerating the aqueous outflow pathway of an eye of a patient also are provided.

A cosmetic composition for skin whitening, wrinkle improvement or skin regeneration includes, as an active ingredient, exosomes derived from stem cells comprising proliferating stem cells.

Embodiments of the invention is directed to methods of forming a bone-like material, by placing a matrix into a culture container, adding cells to the matrix, placing the tissue-cell construct into the culturing environment and incubating the construct under appropriate conditions for the time required to produce an amount of bone-like material of sufficient volume to be harvested for further processing. Other embodiments of the invention are directed to the use of the bone-like material formed by methods of the invention in implantation procedures.
