Electrophysiological properties of ASC and of the derived in vitro-differentiated adipocytes.

Electrophysiological analysis was performed on ASC and their corresponding in vitro-differentiated adipocytes in patch clamp condition. RMP: resting membrane potential. Cm: membrane capacitance. Gm and Gm/Cm: total and specific membrane conductance, respectively. Vth: voltage threshold of activation of the three types of K+ currents investigated (IBK, IKs and IKir). K+ current activation time constant (τ) for IBK and IKs and current density IBK/Cm and IKs/Cm values have been obtained at 50 mV and IKir/Cm at −110 mV. Mean ±SE values are reported. Student's t test was applied to compare paired samples: **,***PKir: S-ASC (n = 17), V-ASC (n = 18), S-ADIPO (n = 28), V-ADIPO (n = 24). mV: milli Volt; pF: pico Faraday; nS: nano Siemens; ms: milli seconds; pA: pico Ampere.
