ATP Release from Mast Cells by Physical Stimulation: A Putative Early Step in Activation of Acupuncture Points

Figure 1

Time course of ATP release (a) and intracellular Ca²⁺ responses (b) induced by 50% hypotonic shock of HMC-1 cells in Ca²⁺-containing (filled squares (𝑛=4) or solid line (𝑛=7), resp.) and in Ca²⁺-free solutions (open circles (𝑛=3) of broken line (𝑛=3), resp.). Data represent averages of 𝑛 measurements ± SEM. The respective curves in (a) and (b) are not significantly different on the basis of 𝑃>0.05.
