1. Esophageal tissue histology.
Esophageal tissue histology. (A) Longitudinal sections of Desmin-stained tissue (×1 magnification) showing tissue layers: muscularis externa (ME), which is composed of longitudinal muscle (LM) and circular muscle (CM); submucosa (SM); muscularis mucosa (MM); lamina propria (LP); and epithelium (EP). (B) Longitudinal sections of Desmin-stained tissue (×20 magnification) illustrating diameter measurement of skeletal muscle fiber cross sections. (C) Longitudinal sections of DAPI-stained tissue (×10 magnification) used to assess nuclear density. (D) Longitudinal sections of Masson’s trichrome–stained tissue (×20 magnification) for measuring relative fractions of muscle (pink) and collagen (blue).
