Method for preparing immune-tolerized extracellular vesicle containing lactate dehydrogenase band peroxisome proliferator-activated receptor gamma coactivator 1-alpha, and composition comprising the extracellular vesicle
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.
EXTRACELLULAR MATRICES WHICH CAN BE USED AS SCAFFOLD FOR LIVING CELLS
The present invention discloses an extracellular matrix comprising a modified polysaccharide consisting of repeating disaccharide units whereby in at least 11% of the disaccharide units one primary alcohol group is oxidized into a carboxylic acid.
Polymeric carriers and methods
Provided are methods of controlling disassociation of cells from a carrier, compositions, and methods of collecting cells. The methods of controlling disassociation of cells from a carrier may include contacting a polymeric carrier with one or more digesting agents to disassociate at least a portion of a plurality of cells from the polymeric carrier. The polymeric carrier may be crosslinked with a crosslinker including at least one of a redox sensitive moiety, a UV light sensitive moiety, a pH sensitive moiety, and a temperature sensitive moiety.
Multi-layer skin substitute products and methods of making and using the same
Provided are live, artificial, skin substitute products and methods of making and using the same, such as for wound treatment and compound testing, including compound testing for efficacy, toxicity, penetration, irritation and/or metabolism testing of drug candidates or compositions such as cosmetics.
HYDROGEL COMPOSITIONS AND METHODS OF USE THEREOF
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.
METHOD OF FORMING SOLID CELL CULTURES
Systems and methods for predicting a patient response to various agents and/or combinations of agents using ex vivo dosing and imaging are disclosed. In one example, a method of forming a solid culture that includes isolating target cells from a patient sample, forming stained cells from the isolated cells by staining the isolated cells with a light-responsive dye; and encapsulating the stained cells in a hydrogel
Micro-physiological organoid culture
The present invention is in the field of the cultivation of biological cells and tissues with organ-like function on a microphysiological scale and provides a method for the microphysiological co-cultivation of 3D organoid tissue and at least one 2D cell layer.
NERVOUS SYSTEM CELL THERAPY
The present invention relates to methods for regenerating nervous system tissue or treating a neurological disorder by administration of a therapeutically effective amount of synthetic tissue containing a cell population of one or more nervous system cell types (e.g., neurons) or multipotent cells (e.g., mesenchymal stem cells), where the cell population is embedded within a modular synthetic hydrogel that is biocompatible. In some preferred embodiments the modular synthetic hydrogel includes a PEG hydrogel crosslinked with a glycosaminoglycan such as hyaluronan.
BIO-INSPIRED TISSUE-ADHESIVE HYDROGEL PATCH AND USES THEREOF
The present disclosure relates to a catechol group- or pyrogallol group-functionalized biocompatible polymer hydrogel patch having excellent biocompatibility and tissue adhesion, and uses for drug delivery, cell transplantation and tissue regeneration using the same. The biocompatible polymer hydrogel patch functionalized with the catechol group or pyrogallol group of the present disclosure has remarkably excellent mechanical properties and tissue adhesion compared with a solution-based bulk hydrogel. Therefore, it can load cells and a drug in vivo for a long time and also safely and efficiently deliver the cells and the drug to a target site.
BIO-INK FORMULATIONS, BIO-PRINTED CORNEAL LENTICULE, AND APPLICATIONS THEREOF
The present disclosure discloses a xeno-free bio-ink formulation amenable to be printed using a 3D printer. The bio-ink formulation exhibits optimum viscosity in the range of 1690-5300 cP. The present disclosure discloses a bio-printed corneal lenticule obtained from the bio-ink formulation. The bio-printed corneal lenticule as disclosed is of the optimum thickness in the range of 10-500 microns and exhibits transmittance in the range of 80-99%. The present disclosure also discloses a process for preparing the bio-ink formulation as well as for preparing the bio-printed corneal lenticule. Further, the present disclosure discloses a method of treating a corneal defect using the bio-printed corneal lenticule as an implant to treat the corneal defect. The bio-printed corneal lenticule can further be used as a model for in-vitro drug testing and diseases modelling.
