MESENCHYMAL STEM CELL CULTURE PRODUCT AND METHOD FOR PREPARING THE SAME
A mesenchymal stem cell culture product and a method for preparing the same are provided. The method for preparing the mesenchymal stem cell culture product includes the following steps. A predetermined quantity of mesenchymal stem cells is seeded in a flat culture device containing a first cell culture medium. When the mesenchymal stem cells proliferate to a target quantity, the first cell culture medium is replaced with a second cell culture medium, and the second cell culture medium is removed after incubation for 18 to 30 hours. A target cell culture medium is added and incubated for 48 to 72 hours. The target cell culture medium is collected repeatedly. The collected target cell culture medium is filtered and concentrated to obtain the mesenchymal stem cell culture product.
CELL CULTURE METHOD
The present invention provides a culture method capable of maturing an organoid through long-term culture, and suitable for producing a conformational organ. The culture method of the present invention is a method for culturing an organoid and/or cells constituting an organ immobilized in a chamber with a culture fluid perfused, and the culture fluid is perfused in such a manner as to generate a turbulent flow in the chamber.
PROCESSES FOR MAKING AND USING A CELLULAR FIBRONECTIN COMPOSITION
The present application provides methods and processes for making and using a fibronectin composition, as well as methods for treating ocular conditions and/or disorders with the cellular fibronectin composition described herein.
Adult stem cell compositions and methods of identification and isolation
Methods, compositions and cells are provided that identify and isolate a population of adult non-embryonic progenitor cells having multilineage potential, physical diameters of about 2 μm to about 8 μm in size or about 4 μm to about 6 μm, and expressing at least one of the stem cell associated genes among Oct-4, KLF-4, Nanog, Sox-2, Rex-1, GDF-3 or Stella. Methods are also provided that identify and isolate populations, which are subsets or subpopulations of progenitor adult stem cells within the population of the adult stem cells which is a heterogeneous population, the methods including contacting the adult stem cells with a ligand specific for at least one of: CD99, tetraspan, ICAM4, full-length MUC1, and truncated MUC1 receptor, in which a presence of a surface protein on the cells that bind to the ligand identifies the population which is the subset of the differentiated progenitor adult stem cells.
Device for isolating stem cells from fetal tissues
The invention relates to a device for isolating stem cells from fetal tissues, which device has an incubation chamber, at least one pump, at least one reservoir for a tissue break-down solution, at least one reservoir for a rinsing solution, optionally a control unit, optionally a means for removing contaminants, and optionally a means for expansion of the isolated stem cells. The invention further relates to a method for isolating stem cells from fetal tissue, which method comprises, among other things, the mechanical dissociation and the enzymatic digestion of the fetal tissue and optionally density gradient centrifugation for removing contaminants. The device and the method according to the invention are particularly suitable for isolating mesenchymal stem cells from fetal tissues, such as umbilical cord tissue, placenta tissue, or fetal lung tissue.
Method for enhancing expression of insulin like growth factor 1 receptor in mesenchymal stem cell, method for obtaining mesenchymal stem cell, and method for treating brain tissue damage
A method for enhancing an expression of insulin like growth factor 1 receptor in a mesenchymal stem cell is provided. The method includes culturing the mesenchymal stem cell expressing insulin-like growth factor 1 receptor in a medium containing platelet-derived growth factor BB (PDGF-BB) to enhance the expression of insulin like growth factor 1 receptor in the mesenchymal stem cell.
Method for treating thyroid associated ophthalmopathy
Provided is a composition including mesenchymal stem cells as an effective ingredient for prevention, alleviation, or treatment of thyroid-associated ophthalmopathy. A pharmaceutical composition including mesenchymal stem cells as an effective ingredient for treatment of thyroid-associated ophthalmopathy allows patients with thyroid-associated ophthalmopathy to recover from an abnormal increase in hyaluronic acid production in orbital fibroblasts, increased adipocyte differentiation, and increased lipid accumulation, and thus may be useful for the treatment of thyroid-associated ophthalmopathy.
THERAPY FOR INTERSTITIAL CYSTITIS BY PLURIPOTENT STEM CELLS
The purpose of the present invention is to provide a novel medical application using pluripotent stem cells in regenerative medicine. The present invention provides a cell formulation and pharmaceutical composition that are for amelioration and therapy for frequent urination and bladder pain caused by the inflammation of the bladder and that contain SSEA-3 positive pluripotent stem cells isolated from cultured mesenchymal cells or a mesenchymal tissue of a living organism. The cell formulation according to the present invention is considered to be based on a mechanism in which, for example, Muse cells are administered against interstitial cystitis having the abovementioned disorders to be successfully engrafted into affected bladder tissue, whereby the disorders are ameliorated and treated.
COMPOSITION FOR PREVENTING OR TREATING RENAL DISEASES, COMPRISING EXOSOMES DERIVED FROM PRECURSOR CELLS OF INDUCED PLURIPOTENT STEM CELL-DERIVED MESENCHYMAL STEM CELLS
The present invention relates to a pharmaceutical composition for preventing or treating renal diseases, comprising, as an active ingredient, exosomes isolated from precursor cells of induced pluripotent stem cell-derived mesenchymal stem cells, the precursor cells having been treated or not having been treated with a pretreatment material. Exosomes of the present invention exhibit an effect of preventing or treating renal diseases that is more improved than that of exosomes isolated from conventional mesenchymal stem cells, thereby being effectively usable for relevant research and development and productization.
COMBINATORIAL CANCER IMMUNOTHERAPY
Provided herein are methods and compositions for dynamically controlling and targeting multiple immunosuppressive mechanisms in cancer. Some aspects provide cells engineered to produce multiple effector molecules, each of which modulates a different immunosuppressive mechanisms of a tumor, as well as methods of using the cells to treat cancer, such as ovarian, breast, or colon cancer.
