abstract |
The present invention relates to compositions, apparatus, and methods for improving the viability of cells, including, but not limited to, nonexcitable cells, and tissues expressing exogenous polynucleotides that encode membrane proteins that regulate that flow of ions across the cell membrane. The viability of the cells and tissues may be improved by contacting the cells or tissue with one or more ion channel blocking agents. Membrane proteins that regulate the flow of ions across the cell membrane include, but are not limited to, ion channels. |
