    Summary A Meckel's diverticulum is the result of an incomplete obliteration of the omphalomesenteric, or vitelline, duct. The duct connects the midgut to the yolk sac of the developing intestinal tract and normally atrophies by the eighth to ninth week of gestation. This event fails to occur in approximately two percent of the population, resulting in the congenital anomaly named after Johann Friedrich Meckel, who first characterized this diverticulum in 1809. Our patient presented with signs and symptoms consistent with a small bowel obstruction secondary to an incarcerated hernia, and underwent emergent laparotomy. An ischemie small bowel segment with a Meckel's diverticulum was resected. Pathology revealed ectopic pancreatic tissue within the diverticulum. Meckel's diverticula have been observed among the contents of hernia sacs in various locations including the inguinal, femoral, and umbilical regions. We report a case of a Meckel's diverticulum presenting in a spontaneous ventral (epigastric) hernia.

    Summary The distribution of sclerotome and neural crest cells of avian embryos was studied by light and electron microscopy. Sclerotome cells radiated from the somites towards the notochord, to occupy the perichordal space. Neural crest cells, at least initially, also entered cell-free spaces. At the cranial somitic levels they moved chiefly dorsal to the somites, favouring the rostral part of each somite. These cells did not approach the perichordal space. More caudally (i.e. trunk levels), neural crest cells initially moved ventrally between the somites and neural tube. Adjacent to the caudal half of each somite, these cells penetrated no further than the myosclerotomal border, but opposite the rostral somite half, they were found next to the sclerotome almost as far ventrally as the notochord. However, they did not appear to enter the perichordal space, in contrast to sclerotome cells. When tested in vitro, sclerotome cells migrated towards notochords co-cultured on fibronectin-rich extracellular material, and on collagen gels. In contrast, neural crest cells avoided co-cultured notochords. This avoidance was abolished by inclusion of testicular hyaluronidase and chondroitinase ABC in the culture medium, but not by hyaluronidase from Streptomyces hyalurolyticus. The results suggest that sclerotome and neural crest mesenchyme cells have a different distribution with respect to the notochord, and that differential responses to notochordal extracellular material, possibly chondroitin sulphate proteoglycan, may be responsible for this.
