The disclosure features methods and compositions for differentiating stem cells into hematopoietic stem and progenitor cells (HSPC) and/or Natural Killer (NK) cells. The methods and compositions described herein are used to differentiate stem or progenitor cells having at least one gene-edit that is maintained in the differentiated cell. Also provided are differentiated cells produced using the methods and compositions described herein for therapeutic applications.

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.

The present invention provides in vitro methods of differentiating brain mural cells and methods of use, including use in blood brain barrier models. Suitable in vitro derived cell populations of brain mural cells are also provided.

The present invention relates to ex vivo methods for obtaining populations of human keratinocytes derived from human pluripotent stem cells.

Described herein are methods and compositions related to treating and preventing an engraftment arrhythmia with an effective amount of amiodarone and ivabradine. Also described herein is a method of cardiomyocyte transplant, the method comprises: dministering in vitro-differentiated cardiomyocytes to cardiac tissue of a subject in need thereof; and administering to the subject an amount of amiodarone and an amount of ivabradine effective to reduce engraftment arrhythmia in the subject.

Provided herein are methods for the differentiation of pluripotent stem cells to committed cardiac progenitor cells. Further provided herein are methods for the use of the committed cardiac progenitor cells in the treatment of cardiac disorders.

A bioreactor device includes a solid substrate having a first face and a second face. The solid substrate at least partially defines a perfusion channel, a plurality of chambers, a fluidic inlet, and a fluidic outlet. A first sheet disposed over the first face and a second sheet disposed over the second face. Characteristically, the combination of the solid substrate, the first sheet and the second sheet define the perfusion channel and each chamber of the plurality of chambers. The plurality of chambers are arranged in rows of chambers in which adjacent chambers are positioned at opposite side of the perfusion channel. The perfusion channel extends from the fluidic inlet and the fluidic outlet having a serpentine path along each row of chambers with each chamber being in fluid communication with the perfusion channel.

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 specification provides a method of producing induced functional astrocytes (iAs) from human pluripotent stem cells substantially more rapidly than previously achieved. These iAs express biomarkers and have functional characteristics typical of natural astrocytes. The iAs are useful in the exploration of astrocyte biology, pathophysiology, and in models of neurologic diseases and disorders.

Methods for differentiating human pluripotent stem cells to dorsal neuroectoderm progenitors and further to glial progenitor cells and oligodendrocyte progenitor cells (OPCs) using inhibitors of BMP signaling and MAPK/ERK signaling are provided. Also provided are cells and cellular compositions obtained by such methods, and uses of such cells. Further provided are methods and protocols for efficiently differentiating human pluripotent stem cells to OPCs in the absence of the ventralizing morphogen SHH or a SHH signaling activator. The methods of the present disclosure reproducibly produce dorsal neuroectoderm progenitor cells by day 7 of the differentiation process, glial progenitor cells by day 21 of the differentiation process and OPCs by day 42 of the differentiation process.
