The present invention relates to a process for producing a population of cells which comprises mature atrial cardiomyocytes. The process comprises the step of treating iPS cells according to a treatment regimen which comprises contacting the iPS cells with Gremlin2 and retinoic acid, such that at least a portion of the iPS cells differentiate into mature atrial cardiomyocytes.

Disclosed herein are synthetic leathers, artificial epidermal layers, artificial dermal layers, layered structures, products produced therefrom and methods of producing the same.

The present invention provides methods to promote the differentiation of pluripotent stem cells. In particular, the present invention provides an improved method for the formation of pancreatic endoderm, pancreatic hormone expressing cells and pancreatic hormone secreting cells. The present invention also provides methods to promote the differentiation of pluripotent stem cells without the use of a feeder cell layer.

The present invention relates to methods for differentiating stem cells into ventral midbrain dopaminergic progenitor cells, and into mesencephalic dopaminergic neurons, and compositions, kits, and uses thereof.

This document relates to bioengineering and involves bioengineered thymus organoids and related humanized animal models. The thymus organoids and animal models have various commercial and clinical uses, including generating humanized antibodies, making antigen-specific human T cells, inducing transplantation tolerance, rejuvenating thymus functions, and modeling human diseases.

The present invention relates to a method, which patterns 3D organoids prepared from human pluripotent stem cells and chops the same so as to culture oligodendrocyte progenitor cells, and induces the differentiation thereof so as to obtain a large quantity of finally differentiated oligodendrocytes. Compared to cells differentiated by a conventional differentiation method, oligodendrocytes obtained in a large quantity have the same or superior reproducibility, stability, and functionality and have remarkably shortened differentiation time, and thus are expected to be very useful for cell therapeutic agents or for screening for therapeutic drugs.

Methods for generating human committed midbrain neural stem cells (NSCs) and midbrain neural progenitor cells (midbrain NPCs) from human pluripotent stem cells are provided using chemically-defined culture media that allow for generation of the midbrain NPCs in as little as six days. The midbrain NPCs can be further differentiated to mature dopaminergic neurons. Culture media, isolated cell populations and kits are also provided.

Methods of generating spinal cord glutamatergic interneurons (V2a interneurons) from human pluripotent stem cells (hPSCs) are provided. A method of the present disclosure may include culturing a first population of hPSCs in vitro in a neural induction medium that includes: a retinoic acid signaling pathway activator; a sonic hedgehog (Shh) signaling pathway activator; and a Notch signaling pathway inhibitor, wherein the culturing results in generation of a second population of cultured cells containing CHX10+ V2a interneurons. Also provided are non-human animal models that include the hPSC-derived spinal cord glutamatergic interneurons, and methods of producing the non-human animal models.

Among the various aspects of the present disclosure is the provision of methods and compositions for the generation of functionally mature beta cells having enhanced SIX2+ activity and therapeutic benefit and uses thereof. An aspect of the present disclosure provides for a method of generating SIX2-enhanced SC-β cells. In some embodiments, the method comprises providing a population of SC-β cells (or EP cells); providing a SIX2 positive regulator; and/or incubating the population of SC-β cells and the SIX2 positive regulator.

The present invention relates to 3D brain organoids, uses thereof, methods and culture medium for generating such organoids. An aspect of the invention provides brain organoids and methods of generating such organoids with bilaterally symmetric optic vesicles, containing both neuronal and non-neuronal cell types, and exhibiting functional circuitry. These organoids can be generated within short time intervals (e.g., 50 days) and therefore are useful for medical modelling and applications.
