Abstract

Visualization of signal transduction in live primary cilia constitutes a technical challenge owing to the organelle's submicrometer dimensions and close proximity to the cell body. Using a genetically encoded calcium indicator targeted to primary cilia, we visualized calcium signaling in cilia of mouse fibroblasts and kidney cells upon chemical or mechanical stimulation with high specificity, high sensitivity and wide dynamic range.

5HT6–G-GECO1.0 can detect an increase in ciliary Ca2+ in NIH-3T3 cells.

The addition of 1 μM ionomycin causes a dramatic increase in fluorescence of 5HT6-G-GECO1.0 in cilia of NIH-3T3 cells. Scale bar is 5 μm. (AVI 10814 kb)

5HT6–G-GECO1.0 can detect ciliary [Ca2+] dynamics in response to ATP stimulation.

The addition of 10 μM ATP induces an increase in both cytosolic and ciliary Ca2+ in NIH-3T3 cells co-transfected with 5HT6-G-GECO1.0 and R-GECO1. The left image is cytosolic R-GECO1. The middle image is of the corresponding cell's cilia expressing 5HT6-G-GECO1.0. The right image is a merged image. The increase in cytosolic Ca2+ can be seen to precede the increase in ciliary Ca2+. Additionally, oscillations in cytosolic and ciliary Ca2+ can be observed in some cells. Scale bar is 10 μm. Video captured at 0.63 Hz. (AVI 116735 kb)

Ca2+ enters the base of the cilia and propagates to the tip after ATP stimulation.

Ca2+ can be seen entering the base of a cilia and traveling to the tip after the addition of 10 μM ATP in NIH-3T3 cells transfected with 5HT6-G-GECO1.0. Scale bar is 5 μm. Video was captured at 1.5 Hz. (AVI 27537 kb)

Dynamic Ca2+ signals detected in primary cilium bent with mechanical flow stimulation.

An upright-positioned primary cilium was subjected with laminar flow corresponding to 1dyne/cm2 shear stress approximately 2 minutes after the start of imaging. Flow was continued for 7.5 minutes before cilium was further imaged for another 4 minutes. Time-lapse imaging was performed at 15-second intervals. Z-projection of xy-planes are presented in this movie. The scale bar corresponds to 5 μm. The scale for the pseudo-colored GFP/ mCherry images has been included in Supplementary Figure 13c.
