Immunohistochemical observations of tissues from both the healthy and periapical granuloma groups. A. Almost no JAK2-positive cells were stained in specimens from the healthy group. B. Slight immunoreactions for p-JAK2 occurred in the healthy group specimens. C. A small number of STAT3-positive cells were observed in healthy group specimens. D. A few p-STAT3-positive cells were stained in the healthy specimens. E. A small number of SCOS3-positive cells were stained in the healthy group specimens. F. Numerous JAK2-positive cells were stained in specimens from the periapical granuloma group. G. Intense immunoreactions for p-JAK2 occurred in the periapical granuloma group. H. A large number of STAT3-positive cells were stained in the periapical granuloma specimens. I. Many p-STAT3-positive cells were observed in periapical granuloma specimens. J. Numerous SCOS3 -positive cells were stained in the periapical granuloma specimens. (original magnification, ×400).
