The present invention relates to an in vitro culture of haematopoietic cells, wherein said haematopoietic cells differentiate to form granulocytes characterised by the ability to kill cancer cells. The invention also relates to said granulocytes, methods for identifying said haematopoietic cells and granulocytes, compositions and kits comprising the same, as well as uses of the same for treating cancer.

Provided herein are methods of producing natural killer (NK) cells and/or ILC3 cells using a three-stage expansion and differentiation method with media comprising stem cell mobilizing factors. Also provided herein are methods of suppressing tumor cell proliferation using the NK cells and/or ILC3 cells and the NK cell and/or ILC3 cell populations produced by the three-stage methods described herein, as well as methods of treating individuals having cancer or a viral infection, comprising administering the NK cells and/or ILC3 cells and the NK cell and/or ILC3 cell populations produced by the three-stage methods described herein to an individual having the cancer or viral infection.

The invention provides methods of differentiating primate pluripotent stem cells into cells of hematopoietic lineage. The invention further provides hematopoietic lineage cells differentiated from primate pluripotent stem cells, as well as methods of using the same and kits comprising the same.

The disclosure encompasses the use of fibroblasts and products derived from fibroblasts for treatment of at least frontotemporal dementia. In particular embodiments, the disclosure teaches administration of cells intravenously, intrathecal or intracerebrally in order to reduce inflammation, enhance neurorgeneration and prevent neuronal dysfunction associated with progranulin abnormalities which characterize frontotemporal dementia. In particular embodiments, the disclosure teaches the utilization of exosomes, or apoptotic bodies derived from fibroblasts. In particular embodiments, the disclosure provides the use of genetically modified fibroblasts in order to augment therapy frontotemporal dementia.

The present invention provides a highly functional hypoimmunogenic cell, namely, a hypoimmunogenic human cell (1) lacking an endogenous gene encoding an α chain of human leukocyte antigen (HLA) class Ia, (2) lacking an endogenous gene encoding HLA class II or an expression regulator thereof, (3) containing an exogenous gene encoding an α chain of HLA class Ib, (4) containing an exogenous gene encoding human PD-L1, and (5) containing an exogenous gene encoding human PD-L2.

In various embodiments methods of producing a cell population enriched for CLEC9A+ dendritic cells are provided where the methods involve culturing stem cells and/or progenitor cells in a cell culture comprising culture medium, a notch ligand, stem cell factor (SCF), FLT3 ligand (FLT3L); thrombopoietin (TPO); and IL-3 and/or GMCSF.

The present disclosure provides multicellular culture models for the study of neuroinflammation, such as to identify novel targets, biomarkers, and therapeutic agents for the diagnosis, prognosis, and treatment of neurodegenerative diseases. Further provided herein are assays for studying neuroinflammation using the present cell culture models.

Provided are the tolerogenic dendritic cells for treating a myocardial infarction and a method for preparing the same, and more particularly, the tolerogenic dendritic cells for treating a myocardial infarction, which can treat cardiac insufficiency that occurs by excessive remodeling of left ventricle in the heart muscle recovery process after an acute myocardial infarction, and a method for preparing the tolergenic dendritic cells. According to the present invention, the inflammatory reaction and the excessive remodeling of left ventricle in the heart muscle recovery process after a myocardial infarction can be inhibited, and thus, the incidence rate of cardiac insufficiency can be significantly reduced, thereby being effectively used for treating a myocardial infarction.

Described herein are methods for the preparation of stable semi-mature tolerogenic dendritic cells and compositions comprising such stable semi-mature tolerogenic dendritic cells. The stable semi-mature tolerogenic dendritic cells described herein and compositions thereof can be used for the establishment of immune tolerance when treating an autoimmune disease, graft rejection and/or graft-versus-host disease.

According to the present disclosure, there is provided a method for producing stem cells including: preparing somatic cells; preparing a chimeric virus including a virus-derived genomic RNA harboring an inducer RNA that induces somatic cells into stem cells and a virus-derived envelope surrounding the genomic RNA, wherein the genomic RNA and the envelope are derived from different viruses; and introducing the inducer RNA into the somatic cells using the chimeric virus.
