The aim of this study was to characterize the functional expression of sodium-calcium exchangers on AFT024 cell line, a murine model of mesenchymal stem/stromal cells (MSCs) supporting human primitive hematopoiesis. All current-clamp and voltage-clamp experiments were performed using the perforated patch whole-cell recording technique with amphotericin B. The membrane potential of -14 mV shifted to -35 mV when lowering the external sodium concentration to 0.

Potassium channels have been involved in epithelial tumorigenesis but the role of small-conductance Ca(2+)-activated K(+) channels is unknown. We report here that small-conductance Ca(2+)-activated K(+) channels are expressed in a highly metastasizing mammary cancer cell line, MDA-MB-435s. Patch-clamp recordings showed typical small-conductance Ca(2+)-activated K(+) channel-mediated currents sensitive to apamin, 4-aminopyridine, and tetraethylammonium.
