An object is to provide a composition and a method for eliminating undifferentiated pluripotent stem cells remaining in a cell group induced to differentiate from pluripotent stem cells. It has been found that while dihydroorotate dehydrogenase inhibitors exhibit cytotoxic activity against pluripotent stem cells, they do not exhibit significant cytotoxic activity against differentiated cells such as somatic stem cells.

Embodiments herein relate to in vitro production methods of hematopoietic stem cell (HSC) and hematopoietic stem and progenitor cell (HSPC) that have long-term multilineage hematopoiesis potentials upon in vivo engraftment. The HSC and HSPCs are derived from pluripotent stem cells-derived hemogenic endothelia cells (HE) by non-integrative episomal vectors-based gene transfer.

The present invention relates in part to nucleic acids encoding proteins, nucleic acids containing non-canonical nucleotides, therapeutics comprising nucleic acids, methods, kits, and devices for inducing cells to express proteins, methods, kits, and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, and therapeutics produced using these methods, kits, and devices. Methods for inducing cells to express proteins and for reprogramming and gene-editing cells using RNA are disclosed. Methods for producing cells from patient samples, cells produced using these methods, and therapeutics comprising cells produced using these methods are also disclosed.

Methods and compositions for the production of cardiomyocytes and cardiac organoids from the differentiation of pluripotent stem cells in three-dimensional (3D) culture are provided. Rock inhibitor, which has been ubiquitously used as a medium supplement to prevent apoptosis during handling and culture of pluripotent stem cells, compromises the capacity of cardiac differentiation of pluripotent stem cells in 3D culture at the most commonly used concentrations.

The invention provides Natural Killer (NK) cells that have a reduced or ablated Signal Regulatory Protein Alpha (SIRPα-) function when compared to a NK cell having an unmodified SIRPα-function that effectively kills a population of cancer cells that express CD47.

Progenitor cells were isolated, purified and expanded using a microfluidic based cell sorting approach. The methods were successfully in purifying cone progenitor cells (CPCs) defined based on a proliferative population expressing cone arrestin and Red/Green (R/G) opsin at greater than 80% using a two multistage approach.

The present invention relates to the field of cell therapy, and specifically relates to a method for producing a mesenchymal stem cell population, the mesenchymal stem cell population and a culture supernatant thereof produced by the method, and a pharmaceutical composition containing such cells or the culture supernatant thereof. The present invention further relates to use of the mesenchymal stem cell population and the culture supernatant thereof for preventing and treating diseases.

As an approach of efficiently inducing differentiation from pluripotent stem cells into insulin-producing cells, provided is a method comprising the step of three-dimensionally culturing cells in a medium containing a dihydroindolizinone derivative.

Provided herein are, in various embodiments, methods and compositions for differentiating olfactory mucosa-derived mesenchymal stem cells (OM-MSC). In certain embodiments, the disclosure provides for media to differentiate OM-MSCs. In still further embodiments, the disclosure provides for methods and compositions using differentiated OM-MSCs for the treatment of nerve repair. In particular embodiments, the disclosure provides for novel treatments of peripheral nerve repair.

The present invention provides a method for producing a retinal progenitor cell, including (1) a first step of subjecting pluripotent stem cells to floating culture in a serum-free medium to form an aggregate of pluripotent stem cells, and (2) a second step of subjecting the aggregate formed in step (1) to floating culture in a serum-free medium or serum-containing medium each being free of a substance acting on the Sonic hedgehog signal transduction pathway but containing a substance acting on the BMP signal transduction pathway, thereby obtaining an aggregate containing retinal progenitor cells.
