Bladder epithelial cells exposed to E. coli

Uropathogenic E. coli elicit a rapid flux in intracellular Ca²⁺ in human bladder epithelial cells (BECs). Shown here is a series of images of Fura-2–loaded BECs before (upper left) and 30 s (upper right), 90 s (lower left), or 300 s (lower right) after exposure to E. coli (see Song et al).
