Episode notes
Cells Have Distinct Electrical Identities
- Every cell type has a characteristic resting membrane potential that correlates with function and proliferative state.
- Cancerous and proliferating cells shift toward much lower (near-zero) potentials, losing their differentiated electrical identity.
Measure Ion Channels, Not Just Genes
- Investigate ion-channel profiles when studying cell state or cancer rather than only genetics.
- Use bioelectric measurements to reveal cell identity and possible reprogramming targets.
Wound Currents Guide Healing
- Wounds short-circuit the skin's bioelectric 'battery' and create a current of injury that guides healing cells.
- The wound electric field diminishes as healing completes and is weaker in older people, linking to slower repair.
