METHOD FOR CULTURING GYNAECOLOGICAL TUMOUR PRIMARY CELLS AND MATCHING CULTURE MEDIUM
A method for culturing primary gynecological tumor cells and culture medium used therein. The method includes using mild cell dissociation reagents to treat a gynecological solid tumor tissue, to ensure the vitality of tumor cells in the tissue to the greatest extent; preparing a special serum-free medium, and using a suspension culture system to culture solid tumor cells derived from a gynecological tumor in vitro to ensure the normal expansion of tumor cells and eliminate interference from normal cells to the greatest extent. The primary gynecological tumor cell culture obtained by the method of the present invention can be used for various cell-based in vitro experiments, second-generation sequencing, construction of animal models, construction of cell lines and the like. It is foreseeable that this culture method has broad application prospects in the fields of gynecological tumor research and clinical diagnosis and treatment.
Methods of engineering human induced pluripotent stem cells to produce liver tissue
Methods are disclosed herein for producing human hepatocytes from human induced pluripotent stem cells. Also provided are transgenic rats for the expansion of human hepatocytes, such as those produced using the methods disclosed herein.
PRIMARY BREAST EPITHELIAL CELL CULTURE MEDIUM, CULTURE METHOD AND USE THEREOF
Provided is a culture medium containing amphiregulin for culturing primary breast epithelial cells and a culture method involving using the medium. In the culturing method, primary cells are cultured on a culture vessel coated with an extracellular matrix gel by using the culture medium, and the primary cells grow on the culture vessel, which has been coated with the extracellular matrix gel, and proliferate rapidly under the combined action of nutrient factors and an extracellular matrix contained in the primary cell culture medium. The cell model obtained by the primary cell culture medium and the primary cell culture method can be used for the evaluating the efficacy of and screening drugs.
PREVENTION AND/OR TREATMENT OF TYPE 1 DIABETES BY AUGMENTATION OF MYELOID SUPPRESSOR CELL ACTIVITY
Disclosed are means, methods and compositions of matter useful for prevention and/or reversion of type 1 diabetes by upregulation of myeloid suppressor cell activity in a mammal suffering from and/or at risk of developing type 1 diabetes. In one embodiment the invention teaches administration of immune cells that have been conditioned by exposure to regenerative cells, and/or cultured in the presence of factors produced from regenerative cells. In one embodiment said regenerative cells are umbilical cord derived mesenchymal stem cells. In one embodiment, immune cells that have been exposed to said regenerative cells are administered together with agents known to enhance myeloid suppressor cell activity. In another embodiment immune cells are administered together with exogenous myeloid suppressor cells.
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.
INDUCTION OF TUMOR VASCULAR NECROSIS UTILIZING FIBROBLASTS
Embodiments of the disclosure concern methods and compositions related to cancer treatment for an individual utilizing recombinant fibroblast cells that comprise one or more activities that are endothelial cell-like. The cells are delivered to a tumor microenvironment following which their death results in destabilization of the tumor vasculature. In particular embodiments, the fibroblast cells recombinantly express one or more of ETV2, FOXC2, and FLI1.
METHODS OF GENERATING HUMAN ENDOMETRIAL STROMAL FIBROBLASTS AND THREE-DIMENSIONAL MULTI-LAYERED HUMAN ENDOMETRIAL TISSUE COMPOSITIONS
Disclosed herein are methods for obtaining endometrial stromal fibroblast cells from pluripotent stem cells, such as induced pluripotent stem cells. The present disclosure also provides methods of obtaining a three-dimensional, multilayered endometrial tissue composition. Methods of using the cells and tissue compositions in drug screening and therapeutic applications are also provided.
Method for introducing hepatocyte growth factor and neurogenin 1 into mesenchymal stem cells
The present invention relates to an adult stem cell line introduced with an HGF gene and a neurogenic transcription factor gene of a bHLH family, a preparation method of the adult stem cell line, a composition for the prevention or treatment of neurological diseases comprising the adult stem cell line, and a method for treating neurological diseases comprising the step of administering the composition to a subject having neurological diseases or suspected of having neurological diseases. The adult stem cells according to the present invention, which are introduced with an HGF gene and a neurogenic transcription factor gene of a bHLH family, can be used to overcome chronic impairment caused by cell death following stroke. Thus, the adult stem cells can be developed as a novel therapeutic agent or widely used in clinical trial and research for cell replacement therapy and gene therapy that are applicable to neurological diseases including Parkinson's disease, Alzheimer disease, and spinal cord injury as well as stroke.
