Figure 6From: Voltage-gated sodium channel expression and action potential generation in differentiated NG108-15 cellsCorrelation analyses among Na v 1.7 mRNA, Na+current density, and action potential frequency in NG108-15 cells. N=23 cells including 7 undifferentiated cells and 16 cells after 21-day differentiation without or with action potential. R is the correlation coefficient.Back to article page
