Disclosed are methods for preparing retinal pigment epithelium (RPE) cells from pluripotent stem cells (PSCs). More particularly, it represents an automated method that combines in a sequential manner three differentiating agents to direct the differentiation of human PSCs into RPE cells.

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.

An object of the present invention is to provide a method of producing an intestinal epithelial cell, which has a large number of cells per area and a high accuracy of kinetic prediction for a CYP3A4 substrate drug such as midazolam, by inducing the differentiation of a pluripotent stem cell, as well as the intestinal epithelial cell, a cell sheet, an evaluation method for a test substance, a screening kit for a test substance, and a cell preparation. According to the present invention, there is provided a production method for an intestinal epithelial cell, including a first differentiation step of differentiating a pluripotent stem cell into an intestinal stem cell, a proliferation step of proliferating the intestinal stem cell obtained in the differentiation step, and a second differentiation step of differentiating the intestinal stem cell obtained in the proliferation step into an intestinal epithelial cell, in which the proliferation step is a step of bringing the intestinal stem cell into a specific state.

Provided are a biomarker identifying method including (1) to (4) and an application thereof. (1) An evaluation value for each of a plurality of biomarkers is derived based on annotation information imparted to each of biomarkers, and a measurement target biomarker is selected based on the evaluation value. (2) The evaluation data of the measurement target biomarker is acquired from the cell A and/or the culture system, before the start of culture of the cell A and/or during the culture. (3) The evaluation data of the discrimination marker of the B cell is acquired from the cell A and/or the culture system, at the final stage of the culture of the cell A and/or after the end of the culture. (4) At least one biomarker indicating characteristics of the cell A is identified from among the measurement target biomarkers, based on the data obtained from (2) and (3).

The present invention provides methods of inducing proliferation of and/or differentiating cells comprising contacting cells with compounds within the methods of the invention. The present invention further provides cells obtainable by the methods of the invention.
