The present disclosure provides a method for generating progenitor T cells from stem and/or progenitor cells comprising exposing the stem and/or progenitor cells to Notch ligand Delta-like-4 (DL4) and vascular adhesion molecule 1 (VCAM-1) under conditions suitable to generate progenitor T cells. The method provided is suitable for in vitro and in vivo pro-T cell generation. In vitro, the pro-T cells are generated under serum-free conditions. Cells produced using the method are provided as well as methods of using same.

Novel MSC stem-cell culture and therapy methods and culture medium compositions for the purpose of inducing, activating, or priming discrete uniform cell phenotypes to selectively promote or suppress inflammation and immunity, yielding polarized, primed, activated, or induced cells used in cell-based therapy.

Disclosed is a polypeptide containing an extracellular domain of a synaptogenic protein, and a method for manufacturing a nerve cell, a complex containing a biotin tagged at the C-terminus of the polypeptide, an artificial synapse inducer for coupling the composite to a streptavidin (SAV)-coated substrate and a nerve cell. The complex tagged with a biotin at the C-terminus of the polypeptide containing the extracellular domain of the synaptogenic protein, such as neuroligin-1, can display activity by being attached to the SAV-coated substrate to adjust the orientation thereof without help of a supported lipid bilayer. The complex containing an additional RFP between the extracellular domain and the biotin of the synaptogenic protein not only facilitates easier mass-production, quantification, and tracking, but also displays activity of a normal synaptogenic protein, thereby inducing excitatory or inhibitory synaptic differentiation by being fixed to the substrate and added to the nerve cell culture.

Methods, compositions and cells are provided that identify and isolate a population of adult non-embryonic progenitor cells having multilineage potential, physical diameters of about 2 m to about 8 m in size or about 4 m to about 6 m, and expressing at least one of the stem cell associated genes among Oct-4, KLF-4, Nanog, Sox-2, Rex-1, GDF-3 or Stella. Methods are also provided that identify and isolate populations, which are subsets or subpopulations of progenitor adult stem cells within the population of the adult stem cells which is a heterogeneous population, the methods including contacting the adult stem cells with a ligand specific for at least one of: CD99, tetraspan, ICAM4, full-length MUC1, and truncated MUC1 receptor, in which a presence of a surface protein on the cells that bind to the ligand identifies the population which is the subset of the differentiated progenitor adult stem cells.

The present invention provides a method for putting a primed pluripotent stem cell in a less differentiated state, a method for producing a pluripotent stem cell having an improved chimera forming ability from a primed pluripotent stem cell, and a method for producing a chimeric animal by using the pluripotent stem cell obtained by any of these methods. The present invention also provides a composition containing a Wnt/ catenin signal inhibitor.

Described herein is a method for producing blood progenitor (hematopoietic progenitor cells) and T cell progenitor cells and to cells produced or obtainable by the process and the use of said cells, the method including: (a) optionally subjecting pluripotent stem cells under conditions that direct the cells to become mesoderm and subsequently hemogenic endothelial cells; and (b) directing hemogenic endothelial cells to differentiate into blood progenitor cells, preferably defined blood progenitor cells) using a media formulation designed to promote endothelial to hematopoietic transition (EHT) while being cultured on a surface functionalised with ligands designed to activate the Notch signaling pathway. In some aspects the ligands are Notch ligands, such as DLL4 and integrin ligands, such as integrin ?4?1 ligand or VCAM1.
