The present invention relates to a method for producing induced natural killer (iNK) cells, into which a chimeric antigen receptor (CAR) gene encoding a CAR is introduced, iNK cells produced by the method, and a cell therapy composition and a pharmaceutical composition for preventing or treating cancer, comprising the iNK cells.

The method according to the present invention has the effects of producing the iNK cells, into which a CAR gene is introduced, with high efficiency through direct reprogramming from isolated cells without limiting an initial cell, and directly producing the same without a differentiation process, thereby simplifying the production process and reducing costs and time. The method according to the present invention has the effect of producing excellent NK cells having enhanced safety by directly producing NK cells from human somatic cells that are easy to obtain, without passing through induced pluripotent stem cells produced through conventional reprogramming technology. In addition, the iNK cells, into which a CAR gene is introduced, produced by the method, have an excellent cancer cell killing ability, and thus can be effectively utilized as a cell therapy composition or a pharmaceutical composition for preventing or treating cancer.

The present invention relates to, inter alia, an engineered cell (e.g., iPSC, IPS-derived NK, or NK cell) comprising a disrupted B2M gene and an inserted polynucleotide encoding one or more of SERPINB9, a fusion of IL15 and IL15Rα, and/or HLA-E. The engineered cell can further comprise a disrupted CIITA gene and an inserted polynucleotide encoding a CAR, wherein the CAR can be an anti-BCMA CAR or an anti-CD30 CAR. The engineered cell may further comprise a disrupted ADAM17 gene, a disrupted FAS gene, a disrupted CISH gene, and/or a disrupted REGNASE-1 gene. Methods for producing the engineered cells are also provided, and therapeutic uses of the engineered cells are also described. Guide RNA sequences targeting described target sequences are also described.

Provided herein are methods and customized media compositions for culturing CIK NKT cells.

The present disclosure provides a method for producing red blood cells by using peripheral blood as well as the produced red blood cells.

The present invention provides a pluripotent stem cell comprising a co-expression vector in which Runx1 and Hoxa9 are of in tandem, and a T cell differentiated therefrom and application thereof. In the present invention, Pluripotent stem cells inducibly co-expressing exogenous Runx1 and Hoxa9 are successfully established by introducing an exogenous vector co-expressing Runx1 and Hoxa9 into pluripotent stem cells. The pluripotent stem cells are directionally differentiated into T-lineage progenitor cells and will be developed into T cells. The pluripotent stem cell-derived T cells obtained by the method of the present invention are not only functionally normal but also have no tumorigenic risk.

Disclosed are compositions, systems and methods comprising a regenerative fibroblast cell, population or subsets thereof possessing regenerative activity useful for treatment of various degenerative diseases. In one embodiment, the disclosure provides fibroblasts with enhanced proliferative potential based on enrichment for CD105 and/or CD117 markers. In one embodiment, fibroblasts possessing CD105 and/or CD117 markers are further enriched for the property of rhodamine 123 efflux.

The present disclosure relates to a method of expanding myeloid progenitor cells by culturing an initial population of cells in a medium comprising a mixture of cytokines and growth factors that promote growth and expansion of the myeloid progenitor cells. The expanded cell population provides a source of cells as therapeutic treatments for neutropenia and/or thrombocytopenia arising in patients subjected to myeloablative therapy and hematopoietic stem cell transplantation.

Methods for the in vitro production of enucleated red blood cells and the enucleated red blood cells thus prepared are provided. Such enucleated red blood cells may express a sortaggable surface protein, which allows for surface modification in the presence of a sortase. Also described herein are surface modified enucleated red blood cells, e.g., conjugated with an agent of interest such as a peptide, a detectable label, or a chemotherapeutic agent, and uses thereof in delivering the agent to a subject.

A method of manufacturing of Natural Killer (NK) Cells genetically modified with lentiviral vectors carrying a polynucleotide coding for a Chimeric Antigen Receptors (CARs). CAR-NK cells obtained with the method, and the use of the CAR-NK cells in medicine, in particular for use in a method of treating cancer is also disclosed.

This invention relates to Natural Killer (NK) cell populations, to methods of producing the same and therapeutic applications thereof. More specifically, the invention relates to the expansion of IMK cells by increasing the expression of specific transcription factors associated with NK cell production.
