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

Figure 2

Time course of ATP release (a) and intracellular Ca²⁺ responses (b) induced by 50% hypotonic shock of HMC-1 cells before (filled square or solid line, resp.) and after treatment with BAPTA (open circles or broken line, resp.) in Ca²⁺-free solution. Data represent averages of 3 measurements each ± SEM. The respective curves in (a) and (b) are significantly different on the basis of 𝑃<0.05.
