Core Tip

Core Tip: Full-thickness biopsies of 1 mm diameter and up to 1 cm length from the human ileum were scanned using two laboratory-based µ-computed tomography setups to study the architecture of the enteric nervous system (ENS) and further scanned by a synchrotron-based end-station for histopathological studies, without any staining. Several pathological neuronal changes, such as vacuolar degeneration, autophagic activity, appearance of sequestosomes, chromatolysis, and apoptosis, were identified in diseased patients. Phenomena that were undetectable by light microscopy were observed. The relationships among various tissue components could be followed in all directions. Thus, this method provides a unique analysis of the ENS.
