Described are cell culture solutions and systems for epithelial stem cell and organoid cultures, formation of epithelial constructs and uses of the same in transplantation.

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.

This invention relates to the production of a population of TCR αβ+ T cells by a method comprising (i) differentiating a population of haematopoietic progenitor cells (HPCs) into progenitor T cells and (ii) maturing the progenitor T cells to produce a population of TCR αβ+ T cells. One or both of steps (i) and (ii) are performed in the presence of Inducible Co-stimulator ligand (ICOS-L). The presence of ICOS-L in steps (i) and/or (ii) may increase expression of αβ T cell receptors and/or increase the proportion of HPCs or progenitor T cells that mature into TCR αβ+ cells. This may be useful for example in the production of T cells for immunotherapy.

Methods of using human airway stem cells in lung epithelial engineering, optionally wherein the cells are contacted with a gamma secretase inhibitor, bioartificial airway organs produced thereby, and the use thereof, e.g., for transplantation. Also methods of treating a bio-artificial matrix with Tenascin-C and/or fibrillin 2.

Disclosed herein are methods and compositions for stimulating angiogenesis, using cells descended from marrow adherent stromal cells that have been transfected with sequences encoding a Notch intracellular domain. Applications of these methods and compositions include treatment of ischemic disorders such as stroke.

The current disclosure describes methods of expanding precursor cells for hematopoietic transplantation in subjects. The methods culture precursor cells in media containing an immobilized high molecular weight LILRB2 agonist or an LILRB2 agonist in combination with a Notch agonist. The expanded cells can be used to treat a variety of hematopoietic disorders.

A method of generating human mature oligodendrocytes is disclosed. The method comprises contacting a cell population which comprises human pre-oligodendrocytes with an inhibitor of the MAPK/ERK pathway under conditions that allow the pre-oligodendrocytes to differentiate into mature oligodendrocytes. Use of the MAPK/ERK pathway inhibitor for treating diseases is also disclosed.

Methods for Generating Neural Crest-Like Cells and Nociceptor-Like Cells from Human Pluripotent Stem Cells are Provided Along with the Related Compositions.

The present invention relates to use of inhibitors of Notch signalling pathway selected from the group consisting of 6-(4-Tert-Butylphenoxy)Pyridin-3-Amine (I3), its derivatives, in treating and/or preventing cancers.

To provide means for efficient growth of epithelial cells capable of being used to manufacture regenerated hair follicle germs. Provided are a culture medium for growth of epithelial cells capable of being used to manufacture regenerated hair follicle germs, the culture medium comprising basal medium and at least (1) through (3), below: and a method for growing the epithelial cells using the culture medium: (1) at least one species of BMP inhibitor: (2) at least one species of fibroblast growth factor: and (3) at least one species of sonic hedgehog (SHH) and/or SHH agonist.
