Abstract: The present disclosure generally relates to, inter alia, a class of chimeric switch receptors containing an endodomain of an IL-9 receptor, engineered to modulate transcriptional regulation in a ligand-dependent manner. The disclosure also provides compositions and methods useful for producing such receptors, nucleic acids encoding same, host cells genetically modified with the nucleic acids, as well as methods for modulating gene expression, modulating an activity of a cell, and/or for the treatment of various health conditions or diseases.

Abstract: This invention relates to compositions and uses of genome edited iPSCs and cells derived therefrom. In particular the iPSCs and cells derived therefrom and compositions comprising the same according to the present invention may be used in cell-based therapies for tissue repair or regeneration. The invention relates to the treatment and/or prevention of injury to the myocardium, and/or ischemia reperfusion injury in the myocardium and other vascularized tissues.

Abstract: The present invention relates to a method for fabrication of a three-dimensional lung organoid comprising human stem cell-derived alveolar macrophages. Specifically, a lung organoid is fabricated by co-culturing cells not expressing the definitive endoderm marker CRCX4 according to a fabrication method of the present disclosure. The lung organoid comprises type 1 and type 2 alveolar epithelial cells as well as alveolar macrophages and realizes infectious or inflammatory responses unlike conventional lung organoids that contain no immune cells and as such, can be advantageously used in studying mechanisms of related lung diseases, excavating biomarkers, developing therapeutic agents, and so on.

Abstract: Described herein is an animal model useful for identifying therapeutic agents that can inhibit the physiological effects or symptoms of COVID-19 infection, including the effects of the following on one or more organs of the animal: inflammation, oxidative stress, fibrin deposition, blood brain barrier breakdown, clotting, and vascular problems.

Abstract: The present disclosure provides engineered immune cells and methods for their creation and use. The immune cells comprise activating and blocking receptors. The signals of the activating and blocking receptors can be modulated via the identity of a hinge.

Abstract: The present invention relates to processes for producing compositions for the cryopreservation of biological materials, e.g. cells and proteins. The compositions comprise a polyampholyte polymer. The invention also provides certain cryopreserving compositions comprising the polyampholyte polymer.

Abstract: The present invention relates to a composition for inducing dedifferentiation form somatic cells to induced pluripotent stem cells (iPSs) and method of inducing dedifferentiation using same, wherein the composition for inducing dedifferentiation and the method of inducing dedifferentiation increases the efficiency of dedifferentiation from somatic cells to iPSs by stimulating CXC chemokine receptor 2 (CXCR2), which is a receptor on human somatic cells, and thus may be effectively used for inducing the dedifferentiation to iPSs.

Abstract: Described herein are methods for enhancing the nuclear reprogramming of somatic cells to become induced pluripotent stem cells. In particular, the methods disclosed herein involve the use of damage-associated molecular pattern molecules (DAMP). In certain embodiments the DAMPs are aluminum compositions such as aluminum hydroxide. Such DAMPs have unexpectedly and surprisingly been found to enhance the nuclear reprogramming efficiency of the reprogramming factors commonly used to induce somatic cells to become induced pluripotent stem cells. Accordingly, this disclosure describes methods of nuclear reprogramming as well as cells obtained from such methods along with therapeutic methods for using such cells for the treatment of disease amendable to treatment by stem cell therapy; as well as kits for such uses.

Abstract: Compositions and methods for conditionally regulating activities of CRISPR-Cas systems. In some embodiments, the methods comprise providing an inactive guide RNA comprising a regulatory domain bound by a lock nucleic acid different from the guide RNA; and displacing the lock nuclei acid from the regulatory domain by a trigger nucleic acid, thereby activating the guide RNA, wherein the activated guide RNA forms a complex with a Cas enzyme.

Abstract: The invention provides a method for the generation of a layered cellular 3 D microtissue aggregate, comprising the steps of contacting myeloid cells with a protein kinase C agonist, yielding primed myeloid cells; incubating the primed myeloid cells in the presence of LDL in a confined volume, particularly in a hanging drop culture; yielding a 3 D culture of myeloid cells; and incubating the 3 D culture together with fibroblasts in a hanging drop in the presence of LDL, yielding the layered cellular aggregate.

Abstract: The present invention relates to methods and composition for use in the treatment of retinal degeneration, in particular retinal degeneration due to retinal pigment epithelium dysfunction.

Abstract: The present invention provides a non-naturally occurring dendritic-like myeloid leukaemia cell according to ATCC Patent Deposit Designation PTA-123875, and methods and kits utilising such cells.

Abstract: The object of the present invention is to provide a method for incorporating an arbitrary protein, lipid, carbohydrate, or nucleic acid into an exosome. The object can be solved by a method for preparing an exosome, comprising the steps of: (a) adding a biological toxin having a perforating activity to a medium containing cells and incubating the mixture, (b) adding ATP and incubating the mixture, and (c) adding a medium containing calcium ion and incubating the mixture.
