Fig. 7From: Desmin gene expression is not ubiquitous in all upper airway myofibers and the pattern differs between healthy and sleep apnea subjectsMuscle cross-sections from an OSA patient stained for desmin (DES, green, A, D, G), desmin mRNA (red, B, E, H), and merged staining with DAPI (nuclei blue) (C, F, I). A–C show a fiber with a region lacking DES but having a dense immunoreaction for its mRNA (arrows). D–F show a vacuole-like structure lacking immunostaining for DES and its mRNA (arrows). G–I show a circular area within the fiber having a very low expression of the DES but normal expression of desmin mRNA (arrows). Scale bar = 25 µmBack to article page
