Methods of preventing and/or treating ischemia, organ dysfunction and/or organ failure, including multiple organ dysfunction syndrome (MODS), and necrosis and apoptosis associated with organ dysfunction/failure, are provided. For instance, the methods involve contacting organ(s) with an oxygenated cholesterol sulfate (OCS), e.g. 5-cholesten-3,25-diol, 3-sulfate (25H-C3S). The organ(s) may be in vivo (e.g. in a patient that is treated with the OCS) or ex vivo (e.g. an organ that has been harvested from a donor and is to be transplanted).

The present method relates to methods of expanding or increasing stem cell production obtained from donor samples. The methods preferably including the steps of harvesting cells from minimally manipulated tissue using multiply harvesting cycles to increase the number of obtained stem cells.

The present invention relates to a composition for inducing differentiation into insulin-producing cells, and a method for inducing differentiation into insulin-producing cells. By using a differentiation inducing composition according to an exemplary embodiment or a differentiation inducing method according to an exemplary embodiment, insulin-producing cells can be prepared in a short period by effectively inducing the differentiation of various types of stem cells into insulin-producing cells, and can be mass-produced in a relatively simple manner, and thus a pharmaceutical composition for preventing or treating diabetes mellitus, comprising insulin-producing cells and/or insulin produced thereby, can be provided.

Progenitor cells were isolated, purified and expanded using a microfluidic based cell sorting approach. The methods were successfully in purifying cone progenitor cells (CPCs) defined based on a proliferative population expressing cone arrestin and Red/Green (R/G) opsin at greater than 80% using a two multistage approach.

The purpose of the present invention is to provide a chondrocyte culture with high tissue regeneration ability. This purpose is met by a method involving a step in which a cell population separated from cartilage tissue is cultured on a thermoreversible polymer.

Provided herein is a method for making a tissue engineering scaffold. The method includes layering at least one sheet of cells onto a flexible scaffold, casting the sheets into geometries, and thereby creating the tissue engineering scaffold. Preferred geometry are non-linear (i.e. not a substantially flat surface such as may be provided by a flat glass substrate). The flexible scaffold is characterized by tensile strength, viscosity, stress, strain, modulus of polymers, or any combination thereof.
