Abstract: Provided herein are, in various embodiments, methods and compositions for differentiating olfactory mucosa-derived mesenchymal stem cells (OM-MSC). In certain embodiments, the disclosure provides for media to differentiate OM-MSCs. In still further embodiments, the disclosure provides for methods and compositions using differentiated OM-MSCs for the treatment of nerve repair. In particular embodiments, the disclosure provides for novel treatments of peripheral nerve repair.

Abstract: Neurosupportive materials that possess strong tissue adhesion were synthesized by photocrosslinking two polymers, gelatin methacryloyl (GelMA) and methacryloyl-substituted tropoelastin (MeTro). The engineered materials exhibited tunable mechanical properties by varying the GelMA/MeTro ratio. In addition, GelMA/MeTro hydrogels exhibited 15-fold higher adhesive strength to nerve tissue ex vivo compared to traditionally used fibrin-based materials. Furthermore, the composites were shown to support Schwann cell (SC) viability and proliferation, as well as neurite extension and glial cell participation in vitro, which are essential cellular components for nerve regeneration. Finally, subcutaneously implanted GelMA/MeTro hydrogels exhibited slower degradation in vivo compared with pure GelMA, indicating its potential to support the growth of slowly regenerating nerves.

Abstract: An embodiment is a scientific fluidic device and a method of assembly of single and multilayer fluidic devices via laser cut and assembly of double sided adhesives. The device includes a member defining a cavity and having two sides, both sides including an adhesive compound, and at least one substrate defining at least two plenums and coupling to the member, forming a flow path. The components of the fluidic device are produced via laser cut and assembly methods. The fluidic device remains intact via adhesive coupling between the substrate(s), member(s), and membrane(s). Altogether, the fluidic device requires assembly that is efficient and economical, resulting in high throughput manufacturing of the fluidic devices.
