LL-37 (4 µM) increases MG63 intracellular Ca²⁺ concentration monitored by laser-scanning confocal microscopy of Fluo-4-AM-loaded cells in the presence of the L-type Ca²⁺ channel blocker nifedipine (100 nM). Nifedipine was included at the arrow and present throughout the experiment. This trace shows one representative experiment out of two.
