In related-art methods of differentiating pluripotent stem cells into a desired cell type, there has not been established a differentiation induction method using human ES/iPS cells and being stable and highly efficient. The use of complicated culture steps is a large problem. In addition, there are also large problems in, for example, that the speed of cell differentiation is low, and hence long-period culture is required, and that the differentiation efficiency is low, and hence it is difficult to obtain a sufficient number of required cells. A method of inducing differentiation into a desired cell type, which induces differentiation within a short period of time and with high efficiency by the use of a Sendai virus vector capable of expressing a transcription factor, and as required, the use of a pluripotent stem cell in which an expression amount of a POU5F1 protein has been substantially removed or reduced, is provided.

Provided here in are methods of producing induced pluripotent stem cells (iPSCs) and isolated population of produced induced pluripotent stem cells (iPSCs). Also provided herein are methods of treating a subject in need thereof using the produced iPSCs or pharmaceutical compositions comprising the produced iPSCs.

The present disclosure relates to methods for transiently activating temperature-sensitive agents in one or more cells, for example by contacting one or more cells with a temperature-sensitive agent and transiently incubating the cells at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Additionally, the present disclosure relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent and then lowering the subject's core body temperature to a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. The disclosure also relates to methods of contacting one or more cells in a subject with a temperature-sensitive agent, maintaining the subject's surface body temperature at a permissive temperature for inducing an activity of the temperature-sensitive agent in the cells. Further disclosed are methods of treating a subject with a temperature-sensitive therapeutic agent.

A method for producing a cardiomyocyte including preparing a stem cell, introducing a Sendai virus into the stem cell by infection, expressing mRNA for synthesizing an inducing factor from the Sendai viruses in the stem cell to induce a cardiomyocyte from the stem cell.

The present invention relates to: a method for producing immunocytes, specifically induced natural killer T (iNKT) cells that are induced by direct reprogramming of isolated somatic cells, and chimeric antigen receptor (CAR)-iNKT cells into which a CAR gene encoding a CAR is introduced; iNKT cells produced by the method; and a cell therapy composition and a pharmaceutical composition for preventing or treating cancer, comprising the iNKT cells.

The method according to the present invention can produce, through direct reprogramming, iNKT cells or iNKT cells into which a CAR gene is introduced, from isolated cells so as to simplify the production process and shorten production time, thereby reducing costs, to have excellent NKT cell production efficiency, and to ensure safety according to the production without passing through induced pluripotent stem cells, thereby having an excellent NKT cell production effect distinguished from that of a conventional reprogramming technique. In addition, the iNKT cells or iNKT cells into which a CAR gene is introduced, which are produced by the method, have an excellent cancer cell killing ability, and thus can be effectively used as a cell therapy composition or a pharmaceutical composition for preventing or treating cancer.

An isolated RNA molecule includes an artificial microRNA precursor comprising in the 5′.fwdarw.3′ direction: a first terminal oligonucleotide consisting of AGGCCR (SEQ ID NO: 1) or a nucleotide sequence in which one to three nucleotides in SEQ ID NO: 1 are substituted; a passenger strand oligonucleotide; a first central oligonucleotide consisting of CYG (SEQ ID NO: 2); a second central oligonucleotide consisting of a nucleotide sequence having at least 70% homology with UUGAAUAKAAAU (SEQ ID NO: 3); a third central oligonucleotide consisting of YGG (SEQ ID NO: 4); a guide strand oligonucleotide; and a second terminal oligonucleotide consisting of UGGAYYK (SEQ ID NO: 5) or a nucleotide sequence in which one to three nucleotides in SEQ ID NO: 5 are substituted.

A method of treating neurodegenerative diseases or disorders, especially Parkinson's disease and a method of inducing neural stem cells from peripheral blood mononuclear cells. The induced neural stem cells can express neural stem cell-related genes and differentiate into neurons, astrocytes and oligodendrocytes. The dopaminergic precursors derived from the induced neural stem cells are transplanted into the striatum of the PD mouse models without any sign of tumorigenesis, thereby improving the behaviors of the PD mouse models and slowing down the progression of Parkinson's disease.
