Summary of glibenclamide-sensitive current densities for NHBE cells and hMSC/NHBE heterokaryons. A) Switching from NaCl bath to Na-gluconate bath (Na-Gluc) depletes available Cl⁻ and results in a significant reduction in outward current density in NHBE cells (controls). B) A similar and significant reduction in outward current density was observed for heterokaryons after the switch from NaCl bath to Na-gluconate bath. All measurements were made in the presence of BaCl₂ (n=17 NHBE cells; n=15 heterokaryons). *P < 0.05.
