The present invention relates to anticancer extracellular vesicles, a preparation method therefor, and an anticancer composition comprising same. Immune-tolerized extracellular vesicles containing LDHB and PGC-1α of the present invention provide cancer treatment, suppression of cancer metastasis, and cancer prevention technologies by normalizing cancer cell-specific aerobic glycolysis energy metabolic pathway in which lactate and hydrogen ions, which form a tumor microenvironment favorable for immune evasion, proliferation, metastasis and invasion of cancer cells, are produced, thereby enabling tumors to be effectively removed by means of the immune system of a patient.

The present invention relates to: a method for preparing an induced pluripotent stem cell line from mesenchymal stem cells; and an induced pluripotent stem cell line (deposit number: KCLRF-BP-00318) obtained thereby. Specifically, the method for preparing an induced pluripotent stem cell line, of the present invention, comprises the steps of: (a) obtaining mesenchymal stem cells from a human umbilical cord; (b) forming, from the mesenchymal stem cells, a colony with a medium for dedifferentiation containing an Ecklonia cava extract; and (c) obtaining an induced pluripotent stem cell line by sub-culturing the colony. The induced pluripotent stem cell line according to the present invention was first established by the present inventors, and the pluripotent stem cell line of the present invention can be differentiated into various cells and can treat various diseases or disorders through cell transplant therapy.

Provided herein are, inter alia, methods, compositions, and kits for producing adipocyte populations such as beige adipocyte populations. Also included are methods and compositions for increasing the level of adipocyte populations (e.g., beige adipocyte populations) in a subject, as well as methods and compositions for treating subjects who are overweight, obese, or who have diabetes.

The present application relates to a method of inducing differentiation of stem cells into chondrocytes using an oligopeptide, and a pharmaceutical composition for treating cartilage injury disease containing differentiated chondrocytes obtained by the method.

Provided is a new type serum-free medium. The medium comprises: DMEM with high glucose (the content of glucose being 4.5 g/L), B27, recombinant human basic fibrolast growth factor (b-FGF), nicotinamide, N-2, vinblastine III (conophylline), non-essential amino acid (NEAA), heparin, epidermal growth factor (EGF), hepatocyte growth factor (HGF), a serum replacement (SR), an insulin-transferrin-selenium complex (ITS), and pentagastrin. Inducing differentiation of mesenchymal stem cells into insulin-secretion-like cells can be achieved in six days in one step using the medium.

The present invention relates to anticancer extracellular vesicles, a preparation method therefor, and an anticancer composition comprising same. Immune-tolerized extracellular vesicles containing LDHB and PGC-1α of the present invention provide cancer treatment, suppression of cancer metastasis, and cancer prevention technologies by normalizing cancer cell-specific aerobic glycolysis energy metabolic pathway in which lactate and hydrogen ions, which form a tumor microenvironment favorable for immune evasion, proliferation, metastasis and invasion of cancer cells, are produced, thereby enabling tumors to be effectively removed by means of the immune system of a patient.

The present disclosure relates to a neural cell population, a neural cell-containing preparation, and a method for producing the population and preparation. More particularly, the present invention relates to a neural cell population derived from intraoral mesenchymal cells, wherein a proportion of normal diploid cells is 80% or more, a preparation containing the neural cell population, and a method for producing the population and the preparation.

Compositions, kits, and methods for preparing nutrient compositions are provided. A nutrient composition can be a food composition such as a dairy composition. A nutrient composition may be produced by an engineered cell composition. Compositions, kits, and methods for preparing engineered cell compositions for producing nutrient compositions are also provided. An engineered cell composition may comprise genetically engineered cells, such as genetically engineered mammary or mammary-like cells. An engineered cell composition can be derived from mammalian stem cells, such as non-mammary adult stem cells. Related methods of characterization, such as for characterizing the engineered cell compositions or the nutrient compositions, are also provided.

The present invention describes in vitro methods for producing a cellular composition with in vivo bone forming potential.

Provided herein are, inter alia, methods, compositions, and kits for producing adipocyte populations such as beige adipocyte populations. Also included are methods and compositions for increasing the level of adipocyte populations (e.g., beige adipocyte populations) in a subject, as well as methods and compositions for treating subjects who are overweight, obese, or who have diabetes.
