Module 7: Figure corpus cavernosum oscillations
Synchronous Ca2+ oscillations in the corpus cavernosum.
A meshwork of corpus cavernosum smooth muscle cells loaded with the fluorescent dye fura-2 display regular fluctuations in Ca2+. The response of three cells (black outlines in the first panel in a), which were located 40 μm from each other, reveal the existence of a wave that began in cell 1 (black trace) and then spread to cell 2 (red trace) and cell 3 (blue trace). The delay between each transient was 200 ms, which means that the wave travelled at about 800 μm/s. Reproduced from Hashitani and Suzuki (2004).
