Distribution of HA immune-positive cells in extravasated dots, beside EB, and saline control. a, b, c. Representative immnuofluoresence staining images of HA in each group. There were very few HA labelled cells in dermis of saline-control (a) and BEB (b). However, HA labelled cells in EB dots were expressed more in EB than in BEB and the control (c). The corresponding images below were enlargements of the boxes outlined in a, b and c. Note that the labelled cells were located near the vessels. D, E. The sum fluorescent intensity and the number of HA (+) cells per section were significantly higher in EB than in the control and BEB (** P < 0.01 vs Control; ## P < 0.01, vs BEB)
