Figure 3From: Temporomandibular joint inflammation activates glial and immune cells in both the trigeminal ganglia and in the spinal trigeminal nucleus No changes in the number of resident TG macrophages are induced by injection of CFA in the TMJ. Twenty-four (A, A') or 72 hours (B, B') after CFA injection, Iba1 immunostaining (green) of contralateral (CONTRA) and ipsilateral (IPSI) TG showed no morphological changes of Iba1+ macrophages. Nuclei were labeled with the Hoechst 33258 dye (blue). Scale bars: 20 μm. No differences in either the number (C-E) or in the average cell size (F-H) of Iba1+ macrophages were detected in any of the three TG divisions in inflamed compared to saline-injected rats. Since no significant differences between saline-injected rats at 24 h and 72 h have been observed, data have been pooled together, and shown here as "saline".Back to article page
