Abstract: Differentiation and stability of neural stem cells can be enhanced by in vitro or in vivo culturing with one or more extracellular matrix (ECM) compositions, such as collagen I, IV, laminin and/or a heparan sulfate proteoglycan. In one aspect of the invention, adult mammalian enteric neuronal progenitor cells can be induced to differentiate on various substrates derived from components or combinations of neural ECM compositions. Collagen I and IV supported neuronal differentiation and extensive glial differentiation individually and in combination. Addition of laminin or heparan sulfate to collagen substrates unexpectedly improved neuronal differentiation, increasing neuron number, branching of neuronal processes, and initiation of neuronal network formation. In another aspect, neuronal subtype differentiation was affected by varying ECM compositions in hydrogels overlaid on intestinal smooth muscle sheets. The matrix compositions of the present invention can be used to tissue engineer transplantable innervated GI smooth muscle constructs to remedy aganglionic disorders.

Title: Low viscosity/high conductivity sodium haloaluminate electrolyte
Inventor: BHAVARAJU SAI
IPC: H01M10/0562
Filed: 2014-06-06
Abstract: An additive that is added to the NaAlX4 electrolyte for use in a ZEBRA battery (or other similar battery). This additive has a moiety with a partial positive charge (d+) that attracts the negative charge of the [AlX4]- moiety and weakens the ionic bond between the Na+ and [AlX4]- moieties, thereby freeing some Na+ ions to transport (move). By using a suitable NaAlX4 electrolyte additive, the battery may be operated at much lower temperatures than are typical of ZEBRA batteries (such as, for example, at temperatures between 150 and 200°C). Additionally, the additive also lowers the viscosity of the electrolyte solution and improves sodium conductivity. Non-limiting examples of the additive SOCl2, SO2, dimethyl sulfoxide (DMSO, CH3SOCH3), CH3S(O)Cl, SO2Cl2. A further advantage of using this additive is that it allows the use of a NaSICON membrane in a ZEBRA-type battery at lower temperatures compared to a typical ZEBRA battery.
