ISOLATION OF BONA FIDE PANCREATIC PROGENITOR CELLS
The present invention relates to a method for isolating bona fide pancreatic progenitor cells and to cell populations enriched for bona fide pancreatic progenitor cells.
STEM CELL DERIVED PANCREATIC ISLET DIFFERENTIATION
Disclosed herein are compositions and methods related to differentiation of stem cells into pancreatic islet cells. In some aspects, the methods provided herein relate to generation of pancreatic β cell, α cell, δ cells, and EC cells in vitro. In some aspects, the disclosure provides pharmaceutical compositions including the cells generated according to the methods disclosed herein, as well as methods of treatment making use thereof.
Pancreatic stem cells and uses thereof
The disclosure relates to stem cells and their therapeutic use in the treatment and/or prevention of pancreatic diseases or disorders. Provided herein are compositions comprising c-kit positive pancreatic stem cells and methods of preparing and using c-kit positive pancreatic stem cells for the treatment and/or prevention of pancreatic diseases or disorders.
Composition comprising porous silica particles carrying a cell fate modulating factor
A composition includes porous silica particles to carry a cell fate modulating factor therein. A method for modulating cell fate includes treating various cells with the composition. The cell fate modulating factor is delivered to a stable target receptor, toxicity to subject cells for delivery may be reduced, a fate of the subject cells can be controlled through sustained release of at least 99 wt. % of the cell fate modulating factor.
METHODS FOR AMPLIFYING AND DIFFERENTIATING PANCREATIC CELLS, AND APPLICATION THEREOF
An amplifying method of pancreatic cells is provided. The amplifying method includes performing digestion, resuspension, discontinuous density gradient centrifugation treatment and amplifying treatment sequentially. The mammalian pancreatic duct is used as the source of pancreatic precursor-like cells in the amplifying method, and islet cells and acinar cells in the cell clusters obtained by the discontinuous density gradient centrifugation treatment are removed. It is beneficial to improve the yield of the pancreatic precursor-like cells availably, and avoid the ethical restrictions and possible carcinogenic risks caused by using the embryonic stem cells. The amplifying medium used comprises a reprogramming substance composed of several small molecule compounds. It can avoid the risks of non-specific and off-target deletion that are easily caused by the use of the gene-editing methods to change the gene sequence. Also provided is a differentiation method and an application of the pancreatic precursor-like cells obtained by the amplifying method.
Differentiation of human embryonic stem cells
The present invention provides methods to promote the differentiation of pluripotent stem cells and the products related to or resulting from such methods. In particular, the present invention provides an improved method for the formation of pancreatic hormone expressing cells and pancreatic hormone secreting cells. In addition, the present invention also provides methods to promote the differentiation of pluripotent stem cells without the use of a feeder cell layer and the products related to or resulting from such methods. The present invention also provides methods to promote glucose-stimulated insulin secretion in insulin-producing cells derived from pluripotent stem cells.
BIOARTIFICIAL PANCREAS
A bioartificial device, such as a bioartificial pancreas, for implantation in a patient's vascular system. The bioartificial pancreas includes a scaffold adapted to engage an interior wall of a blood vessel, a cellular complex support by the scaffold and extending longitudinally within the interior cavity of the scaffold so as to be exposed to the blood flow when the scaffold is engaged with the blood vessel, the cellular complex support comprising one or more pockets bordered by thin film; and cellular complex comprising pancreatic islets disposed in the one or more pockets, the thin film being adapted to permit oxygen and glucose to diffuse from flowing blood into the one or more pockets at a rate sufficient to support the viability of the islets. The invention also includes methods of making and using a bioartificial pancreas.
METHODS OF PRODUCING HUMAN FOREGUT ENDODERM CELLS EXPRESSING PDX1 FROM HUMAN DEFINITIVE ENDODERM
Disclosed herein are cell cultures comprising dorsal and/or ventral PDX1-positive foregut endoderm cells and methods of producing the same. Also disclosed herein are cell populations comprising substantially purified dorsal and/or ventral PDX1-positive foregut endoderm cells as well as methods for enriching, isolating and purifying dorsal and/or ventral PDX1-positive foregut endoderm cells from other cell types. Methods of identifying differentiation factors capable of promoting the differentiation of dorsal and/or ventral PDX1-positive foregut endoderm cells, are also disclosed.
Isolation of bona fide pancreatic progenitor cells
The present invention relates to a method for isolating bona fide pancreatic progenitor cells and to cell populations enriched for bona fide pancreatic progenitor cells.
COMPOSITION FOR INDUCING DIFFERENTIATION INTO INSULIN-PRODUCING CELLS, AND USE THEREOF
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.
