From: Expression and significance of HMGB1, TLR4 and NF-κB p65 in human epidermal tumors
Expression of HSP70 in epidermal tumors and normal skin by IHC EnVision (magnification × 400). (a) to (e). Positive expression of HSP70 was located in the epithelial intercellular space as shown by the red arrows. (f). **P <0.01 as compared HSP70 in the epithelial intercellular spaces in SCC. The error bars represent the standard error of the mean (SEM).
