SOCE is associated with the induction of transcellular Ca²⁺ waves. A, Representative images of a depletion-induced Ca²⁺ wave that is initiated in both processes with propagation into the cell body. B, [Ca²⁺]_i increases during the [Ca²⁺]_i wave for each compartment (n = 19). C, D, The propagation velocity and rise time (time required for SOCE-mediated [Ca²⁺]_i increase from 10% to 90% of maximum) is faster in the end-foot compared with the apical process and the cell body (p < 0.05; n = 20; N = 4).
