Methods and materials relating to cultured choroid plexus organoids comprising: (a) an epithelium comprising a tight epithelial barrier; and/or (b) one or more cysts surrounded by an epithelium, plus other authentic features and markers.

Disclosed is a method of promoting neuronal growth by administering IGFBPL-1, or an agent that increases or stabilizes IGFBPL-1 activity to a subject in need thereof, e.g., a subject in need of treating optic nerve degeneration.

The present invention provides elastic assemblies used to model tissues or organs of interest. In one embodiment, detailed herein, the assemblies are designed to model the blood brain barrier following a traumatic brain injury. The present invention also provides elastic membranes on which the assemblies are built, kits from which the assemblies may be prepared, and systems that expand upon the assemblies, forming more physiologically relevant models. Methods for making and using the disclosed devices are also provided.

An in vitro method of producing a bi- or multi-differentiated tissue with at least two tissue types is provided. The method includes the steps of developing a first tissue to a stage of differentiation of interest; developing a second tissue to a stage of differentiation of interest differing from the stage of differentiation of interest of the first tissue; placing the first and second tissue in a vicinity sufficient for fusion by growth, allowing the first and second tissue to grow and fuse to each other, thereby producing a bi- or multi-differentiated tissue including the first and second tissue with different stages of differentiation; bi- or multi-differentiated tissue obtained by such a method; uses of the tissue and kits for performing the method.

Improved hybrid neurovascular spheroids and methods for making the same are provided. In some embodiments of a method for making a hybrid neurovascular spheroid, the method includes i) propagating cortical cells to form a cortical spheroid; ii) propagating endothelial cells to form an endothelial spheroid; iii) propagating mesenchymal stem cells to form a mesenchymal cell culture; and iv) combining the cortical spheroid, endothelial spheroid, and mesenchymal spheroid under conditions to form the hybrid neurovascular spheroid.

Disclosed is a method of promoting neuronal growth by administering IGFBPL-1, or an agent that increases or stabilizes IGFBPL-1 activity to a subject in need thereof, e.g., a subject in need of treating optic nerve degeneration.

This invention relates to methods of expanding T regulatory cells through OX40L and Jagged-1 induced signaling. The methods can be used for treating autoimmune diseases.

The invention provides methods of treating diseases, disorders or injuries involving demyelination and dysmyelination, including multiple sclerosis, by the administration of a LINGO-4 antagonist.
