Quantification of current density (pA/pF) at 120 mV in control (37 +- 20, n = 6) and UV-illuminated cells (380 +- 172, n = 8), N = 4. Significance was tested using a two-tailed Mann–Whitney U-test (** P = 0.002). Data presented as mean +- s.d. Center line in the box plot represents the median, the box represents 25–75% of the data, whiskers represent 1.5 x interquartile range and the square box among data points represents the mean. Scale bars, 10 µm.
