Module 3: Figure flow-induced Ca2+ signals



Flow-induced Ca2+ signals in kidney epithelia cells.

Wild-type kidney epithelial cells in culture responded to fluid flow over their surface by an increase in Ca2+ that occurred either immediately (top row of panels) or after a 5 s delay (upper and lower centre rows of panels). Cells carrying a mutation in PKD1 failed to respond to fluid flow (bottom row of panels).
