The present disclosure relates to methods for increasing telomere length in one or more human cells and/or increasing genome stability of one or more human cells, for example by contacting one or more human cells with an agent that increases expression of Zscan4 in the one or more human cells. Methods of treating a subject in need of telomere lengthening, treating a disease or condition associated with a genomic and/or chromosome abnormality, of rejuvenating one or more human cells, of rejuvenating tissues or organs, and of rejuvenating a subject in need thereof, for example by contacting one or more human cells in the subject with an agent that increases expression of Zscan4, or by administering to a subject in need thereof, an agent that increases expression of Zscan4 are also provided.

Compositions comprising donor cells, acceptor cells, membrane-enclosed bodies and methods are described herein.

A method of producing helper T cells, comprising: (i) culturing T cells, which have been induced from pluripotent stem cells and into which a CD4 gene or a gene product thereof has been introduced, in a medium containing IL-2 and IL-15; and (ii) isolating CD40L-highly expressing T cells from cells obtained in step (i).

A composition comprising isolated vascular-associated naturally pluripotent stem cells (vaPS), is disclosed, as well as method of treating defects using such composition, wherein said vaPS are capable of differentiating into somatic cells of all three germ layers under the guidance of the respective microenvironment.

Disclosed herein are compositions and methods to decellularize an isolated organ or portion thereof. Also disclosed herein are compositions and methods for treatment of disease utilizing a decellularized or recellularized organ. Also disclosed herein are methods of improving decellularization and/or recellularization of an isolated organ or portion thereof.

Provided are methods and compositions for obtaining functionally enhanced derivative effector cells obtained from directed differentiation of genomically engineered iPSCs. The derivative cells provided herein have stable and functional genome editing that delivers improved or enhanced therapeutic effects. Also provided are therapeutic compositions and the use thereof comprising the functionally enhanced derivative effector cells alone, or with antibodies or checkpoint inhibitors in combination therapies.

Disclosed are subpopulations of mammalian stem cell- or mammalian progenitor cell-derived cardiomyocytes. The subpopulations of cardiomyocytes contain a portion of a population of mammalian stem cell- or mammalian progenitor cell-derived cardiomyocytes. The subpopulations of cardiomyocytes can be CD36.sup.+ subpopulations or CD36.sup.− subpopulations. Disclosed are methods of isolating and of using the subpopulations of cardiomyocytes, particularly in cardiac disease modeling, drug screening, cardiotoxicity testing, and cardiac regeneration/repair.

The present invention relates to a stable method for introducing at least one inducible cassette into a cell, and permitting controllable transcription from within that inducible cassette. The method may be used for any cell type, from any eukaryotic organism, but has a particular application in the introduction of inducible cassettes into pluripotent stem cells, such as animal or human pluripotent stem cells (hPSCs). The inducible cassette is controllably inserted in such a way to ensure that the genetic material it contains is not silenced or subject to negative influences from the insertion site, and transcription of the genetic material is controlled.
