Calcium, strontium and barium elicit different patterns of exocytosis in chromaffin cells

Secretory responses induced by divalent cations in permeabilized chromaffin cells. AoS

We have studied three divalent cations (Ca2+, Sr2+, Ba2+) capable of eliciting secretion in adrenal chromaffin and other secretory cells. These cations enter the cells through voltage-sensitive Ca2+ channels, yet Ba2+ and Sr2+ are poorly cleared from
