Disclosed herein are method of producing NK cells that include one or more heterologous nucleic acids. The methods include culturing a population of isolated NK cells in the presence of one or more cytokines to produce a population of activated NK cells. The population of activated NK cells are transduced with a viral vector comprising the one or more heterologous nucleic acids, for example by contacting the activated NK cells with viral particles including the viral vector. The resulting transduced NK cells are then cultured in the presence of one or more cytokines, and optionally in the presence of irradiated feeder cells, to produce a population of expanded transduced NK cells. Also disclosed are methods of treating a subject with a disorder (such as a tumor or hyperproliferative disorder) by administering to the subject NK cells produced by the methods described herein.

Methods and compositions directed to altering a population of sRNAs in a sperm using vesicles isolated from an epididymosome are provided. Methods and compositions directed to altering a population of sRNAs in an oocyte using vesicles isolated from an epididymosome are also provided. Methods for altering an sRNA population in a sperm or an oocyte can be used to prevent, or reduce the severity of, a disease, disorder, or condition that would otherwise be inherited by progeny. For example, certain epigenetic inherited conditions due to paternal effects, such as certain metabolic and stress disorders and conditions, can be ameliorated in progeny using sperm or oocytes having an altered sRNA population.

Cells with a mixed mesenchymal stem cell (MSC) and astrocyte phenotype are provided. Pharmaceutical compositions comprising these cells, extracellular vesicles from these cells as well as methods of production and methods of use are also provided.

Provided herein are methods and devices related to inducing a population of self-renewing or senescent stem cells, to produce one or more beneficial factors for the treatment of a disease or disorder in an individual. Also provided are compositions and methods for inducing senescence, useful for inducing senescence in a population of stem cells, in order to produce one or more beneficial factors for the treatment of a disease or disorder in an individual. Methods and devices to control and customize the production of the beneficial factors for the requirements of a disease or disorder being treated are described. Also provided are factor production units for the production of the beneficial factors, and devices for the delivery of the beneficial factors to an individual in need.

This disclosure provides, among other things, amplifiable nucleic acid constructs for expressing a gene of interest in a cell, e.g., an erythroid cell. The amplifiable nucleic acid construct may contain the gene of interest and an RNA-dependent RNA polymerase (RdRP)-responsive 5′ UTR, and may optionally further contain an RdRP-responsive 3′ UTR. RdRP may also be provided, e.g., on the same construct or a different construct.

Disclosed herein are human hepatocytes for example isolated human hepatic progenitor cells, artificial tissue or organ thereof, and kits or compositions thereof. Also disclosed herein are various methods of using a human hepatocyte disclosed herein.

The present disclosure provides methods and compositions for genetically modifying lymphocytes, for example T cells and/or NK cells, in shorter times than previously and/or in whole blood or a component thereof. In some embodiments a lymphodepletion filter assembly is used before or after forming a reaction mixture where lymphocytes are contacted with recombinant retroviral particles in a closed system, to genetically modify the lymphocytes.

This disclosure relates to methods of treating or preventing heart malformations or cardiovascular diseases comprising administering an effective amount of thyroid hormone in combination with i) an agent that decreases DUSPS and/or DUSP6 expression and/or ii) a beta-adrenergic blocking agent to a subject in need thereof. In certain embodiments, this disclosure relates to in vivo and in vitro methods of inducing proliferation of cardiomyocytes using agents or combinations of agents disclosed herein.

This invention relates to exosome compositions and methods of using them.

Methods are disclosed herein for treating glaucoma in a subject. In some embodiments, the methods increase retinal ganglion cell survival. The disclosed methods use exosomes and/or miRNA.
