Umbilical cord-derived adherent stem cells, preparation method therefor, and use thereof
Disclosed are enhanced umbilical cord-derived adhesive stem cells, a preparation method therefor, and a use thereof. The enhanced umbilical cord-derived adhesive stem cells have an anti-inflammatory effect, a blood vessel regeneration effect, or a nerve regeneration effect, thereby being usable in a pharmaceutical composition or a cell therapeutic agent for treating or preventing various diseases.
Formulation comprising extracellular vesicles, method for producing the same, and uses thereof
Disclosed herein is a formulation comprising an extracellular vesicle (EV), and a therapeutic active agent induced or embedded in the EV. According to preferred embodiments of the present disclosure, the EV is isolated from umbilical cord mesenchymal stem cells, and the active agent may be a growth factor, an immune-modulating agent, a small molecule, an siRNA, cDNA or a plant ingredient; for example, curcumin. Also disclosed herein are methods for producing the present formulation, and uses of the present formulation in the treatment of various diseases.
Preparation method of human-derived cardiac stem cell spheroid and use thereof
The present invention relates to a preparation method of a spheroid using human-derived cardiac stem cells and a therapeutic use for ischemic heart disease using the myocardial regeneration effect thereof. The spheroid using the cardiac stem cells provided in the present invention has excellent myocardial differentiation ability and regenerative therapeutic ability as compared to existing cardiac stem cells, and thus may be used for the treatment of ischemic heart disease such as myocardial infarction.
Methods of differentiating stem cell-derived proprioceptors
The presently disclosed subject matter provides for in vitro methods of inducing differentiation of stem cells (e.g., human stem cells) into proprioceptors, proprioceptors generated by such methods, and compositions comprising such proprioceptors. The presently disclosed subject matter also provides for uses of such proprioceptors for preventing and/or treating disorders of proprioceptor neurons and/or neurodegenerative disorders (e.g., Friedreich's Ataxia).
Recombinant adipose-derived stem cell and recombinant method thereof
The present invention provides a recombinant adipose-derived stem cell and a recombinant method thereof, and belongs to the technical field of genetic engineering, where an adenovirus carrying an hFIX gene is transfected into an adipose-derived stem cell to obtain the recombinant adipose-derived stem cell. In the present invention, an adenovirus carrying an hFIX gene is transfected into an adipose-derived stem cell, and the recombinant adipose-derived stem cell obtained after the transfection can express an hFIX protein.
GENETICALLY MODIFIED HUMAN STEM CELL EXPRESSING A MUTANT HUMAN CYTOCHROME P450 2B6 PROTEIN AND USE THEREOF IN THE TREATMENT OF CANCER
The present invention relates to a genetically modified human stem cell, in which said human stem cell comprises an exogenous nucleic acid comprising a region coding for a fusion protein comprising a mutant human cytochrome P450 2B6 (CYP2B6*) protein of SEQ ID No. 1 or a variant or fragment thereof and an NADPH-cytochrome P450 reductase protein of SEQ ID No. 2 or a variant or fragment thereof, functionally bound to a promoter, said exogenous nucleic acid having been integrated into one of the genomic safe harbors of said human stem cell. The invention also relates to the use of said cell for the treatment of cancer and/or cancer recurrences and/or associated metastases, particularly the solid tumours, and in particular the hepatocellular carcinomas and/or associated metastases.
Compositions and methods for modifying cell surface glycans
Methods and compositions for modifying glycans (e.g., glycans expressed on the surface of live cells or cell particles) are provided herein.
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.
MESENCHYMAL STEM CELL EXPRESSING HEPATOCYTE GROWTH FACTOR, AND USE THEREOF
A recombinant lentiviral vector includes a gene encoding a hepatocyte growth factor (HGF) protein. And a cell that is transfected with the lentivirus produced by using the vector is provided. The recombinant lentivirus includes a gene encoding a HGF protein, and a host cell transfected with the lentivirus maintains a high cell proliferation rate. Thus, a mesenchymal stem cell expressing HGF by being transfected with the lentivirus may be usefully employed as a cell therapeutic agent.
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.
