Stress-Induced Mast Cell Activation in Glabrous and Hairy Skin

Figure 3

Comparative analysis of the proportion of degranulated mast cells. (a) In glabrous skin, brief exposure to stress induced a significant increase in the proportion of degranulated mast cells and prolonged exposure to stress was associated with a gradual return to normal value of degranulated mast cells. (b) In hairy skin, acute exposure to stress induced an amplification of mast cell degranulation process that was maintained after prolonged exposure to stress. Error bars represent the standard error of the mean (SEM). ^∗𝑃<0.05, ^∗∗𝑃<0.01, ^∗∗∗𝑃<0.001, two-tailed multiple comparison test.
