Disclosed is a method of manufacturing a medium composition for cell culture, and a method of manufacturing a crushed stem cell extract using a method of manufacturing a medium composition for cell culture and a 3-low extracting method of active ingredients of a stem cell. The medium composition for cell culture includes a basal medium; a hyaluronic acid; and an additive composition. According to an embodiment, when active ingredients of a stem cell are extracted, a stem cell is crushed at a 3-low circumstance of low temperature, low pressure, a hypotonic circumstance.

Provided are a sanal culturing composition and a method for culturing sanal using the same.

The present disclosure relates to a composition for promoting the production of stem cell-derived exosomes or increasing the stemness of stem cells. When the composition of the present disclosure is used in culturing stem cells, the stemness of stem cells and the yield of stem cell-derived exosomes are increased, and thus good-quality stem cells and stem cell-derived exosomes can be produced more efficiently, and accordingly, can be advantageously used in related research and development and commercialization.

Bone marrow containers are described herein. Separation systems for separating activated immune cells from other components are described herein. Methods of activating an immune cell are described herein.

A two-component hydrogel matrix system is provided, which system is useful in a variety of cell growth uses, including without limitation three-dimensional culture systems. The components comprise modified hyaluronic acid (HA); and modified elastin-like proteins (ELP). Variables of HELP, including for example, matrix stiffness, matrix stress relaxation rate, and cell-adhesive-ligand concentration, can be independently and quantitatively specified.

This disclosure describes methods for organoid generation including, for example, for generation of a multi-tissue organoid. The multi-tissue organoid may include cartilage, bone, epithelium, and/or fibrous connective tissue. This disclosure further describes methods for isolating cells from the organoids and methods of using the organoids and cells of the organoids.

Aspects of the present invention include compositions and methods for discovering novel compositions and applying said compositions in treating medical conditions including aging, degenerative disease, wound treatment, and cancer through the modulation of molecular pathways regulating regeneration and senolysis by means of altering the embryonic-fetal and prenatal/postnatal transitional states of mammalian cells.

Disclosed are cell culture scaffolds comprising a scaffold composition comprising chitosan and alginate, hyaluronic acid, or chondroitin sulfate, wherein the scaffold is formed from an aqueous solution comprising greater than 4 wt % chitosan. These scaffolds can be contacted with cells, e.g., patient-derived cancer cells. The scaffolds provide 3D structure allowing appropriate cell function to occur. A scaffold of chitosan and chondroitin sulfate are also disclosed. Scaffold compositions comprising chitosan and alginate, hyaluronic acid, or chondroitin sulfate are also disclosed. Methods of making these scaffolds, e.g., by freeze casting or 3D printing, and using them to evaluate a patient's cancer cell and personalize treatment are also disclosed.

A blood product (10), a method for preparing the blood product, a blood product obtainable by the method and a blood product preparing container means. The blood product comprises components from whole blood, especially fibrin, thrombocytes and leukocytes. The blood product (10) comprises a first layer (21), a second layer (22) and a third layer (23). The second layer (22) is adjacent to the first layer (21) and the third layer (23). The first layer (21) defines a first outer surface (24) of the blood product (10) and the third layer (23) defining a second outer surface (25) of the blood product (10). The first layer (21) comprises a majority of fibrin, the second layer (22) comprises a majority of thrombocytes and the third layer (23) comprises a majority of leukocytes.
