WJ-MSCs express functional BKCa channels. a Western blot for BKCa channel protein expression. b Agarose gel electrophoresis image of KCNMA1 amplified from WJ-MSCs with specific primers by real-time PCR. c Traces of whole-cell recordings of BKCa channels in WJ-MSCs treated with or without 100 nM paxilline. d Membrane currents were activated by 300-ms voltage steps to between − 60 and + 100 from − 80 mV and then to − 30 mV (as shown in the inset). The I-V relationships of the currents under the control conditions and after paxilline treatment are shown
