Fig. 4. Calcium imaging of cell lines treated with thymol (400 μM) or ionomycin positive control (3 μM) show Cal27 cells have TRP channel activity while HeLa cells do not.
A) CHO-TRPA1 cells show a thymol-induced calcium influx. B) CHO-TRPV1 cells do not show an influx of calcium in response to thymol. C) Cal27 cells show a thymol-induced calcium influx. D) HeLa cells do not show an influx of calcium in response to thymol.
