Intramural Ganglion Structures in Esophageal Atresia: A Morphologic and Immunohistochemical Study
Figure 1
Actin-A. (a) Control neonatal esophagus: Anti-A immunostaining marks strongly the muscularis mucosae (A), as well as both the inner (B) and outer (C) muscle layers; (b) Presence of disarranged and fragmented muscle bundles (A) reaching the epithelial basal line and segmental agenesia of muscularis mucosae. (B) Anti-A immunostaining is reduced in the smooth musle bundles of the UEP (c), but it is weaker in (d) the DES.
