Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.

Compositions and methods are provided for modifying the contents of exosomes released by target cells. In one embodiment cell targeted nanoparticles are used to deliver interference RNAs to the target cells which alter the packaging of exosomes released by the target cells.

Disclosed herein are compositions for use in promoting or improving repair or regeneration of damaged tissue or for improving recovery from a viral, bacterial or fungal infection. The compositions include small mobile stem (SMS) cells. Also disclosed are methods of making the compositions, and methods of using the compositions for treating or ameliorating inflammatory illnesses, such as fibrosis or COPD, and/or a viral, bacterial or fungal infection or the damage caused by such pathogens.

The present invention provides a cell culture having a cartilage-like tissue forming property, including a cell population in which the expression intensity of at least one cell surface marker selected from the group consisting of CD166, CD165, CD99, GD2, STRO-1, CD108, CD164, CD6, CD106, and CD107b is not higher than the threshold for each cell surface marker, and/or, the expression intensity of at least one cell surface marker selected from the group consisting of CD26, CD73, CD105, CD44, CD120a, CD201, EGFR, CD146, CD140a, and CD90 is not lower than the threshold for each cell surface marker.

The present disclosure relates to antigen-binding agents that specifically bind to epidermal growth factor receptor variant III (EGFRvIII). Antigen-binding agents of the present disclosure include antibodies and antigen-binding fragments thereof, chimeric antigen receptors (CARs) and bi-specific T-cell engagers (BITE!), bispecific killer cell engagers (BiKEs) and bispecific killer cell engagers (TriKEs). Nucleic acid molecules and vectors expressing antibodies, antigen-binding fragments, CARs, BiTEs, BiKEs or TriKEs are also encompassed by the present disclosure. Immune cells engineered to express CARs, BiTEs, BiKEs or TriKEs may be used to specifically recognize and kill cells expressing EGFRvIII.

The present invention provides methods of inducing proliferation of and/or differentiating cells comprising contacting cells with compounds within the methods of the invention. The present invention further provides cells obtainable by the methods of the invention.
