Enteric Nervous System Development
My laboratory is interested in the development of the enteric nervous system (ENS), a complex neuronal network whose principal function is to maintain normal intestinal motility. Congenital abnormalities of the ENS are responsible for severe gastrointestinal disorders in childhood, including Hirschsprung’s disease, intestinal pseudo-obstruction, and other causes of dysmotility. The ENS is made up of neurons and glia that arise from the neural crest and migrate along the length of the intestine.

In our laboratory we use the avian embryo as a model system to study ENS development. Using a variety of techniques, including retroviral-mediated gene misexpression, chick-quail chimeras, coelomic transplantation, and organ culture techniques, we have thoroughly characterized normal development of the colorectal ENS. We have also identified essential roles for bone morphogenetic proteins and endothelin-3 during ENS formation in the hindgut, the portion of intestine most commonly affected in human congenital disorders of the ENS. Ongoing projects include:
Understanding the molecular factors required for normal ENS development will give us new insights into the pathophysiology of neuro-intestinal disorders and allow us to develop novel diagnostic and therapeutic approaches to the management of children with these serious conditions.

Constipation is a common complaint in pediatrics, accounting for 25% of all visits to a pediatric gastroenterologist. While the majority of children improve with diet modification or medications, some suffer from severe constipation that does not respond to conventional therapy. These children often suffer from abdominal pain and bloating, fecal incontinence, absence from school, frequent hospitalizations, and social withdrawal. One of the major causes of this intractable constipation is abnormal colonic motility, where the colon is unable to propel waste products out of the body. This problem is seen in slow transit constipation, irritable bowel syndrome, Hirschsprung’s disease, and other disorders of colonic function. Many individuals of all ages are affected by these conditions. However, despite its prevalence, little is known about the causes of abnormal colonic motility and, as a result, available treatments are limited.
Similarly, children with Hirschsprung’s disease can suffer from severe constipation and bloating even after they have had surgery to remove the part of the colon lacking nerve cells. Their symptoms, which can be severe and very difficult to treat, are often due to abnormal colonic motility or to abnormal anorectal function. In severe cases, children with Hirschsprung’s can develop enterocolitis, a life-threatening inflammation of the intestine. As in other conditions caused by abnormal intestinal motility, the causes are unknown and treatment options are limited.
Intestinal neurons labeled with a neuronal antibody (Tuj1) in red, with their nuclei stained blue (DAPI), form elaborate neuronal networks in vitro.
Dr. Allan Goldstein researches the development of the enteric nervous system, including the causes of distal aganglionosis, causes and possible treatments of Hirschsprung-associated enterocolitis (HAEC), and neuronal cell transplantation, a novel treatment approach for Hirschsprung disease.
The REACH Symposium (Research, Education, and Awareness for Children with Hirschsprung's disease) is a multidisciplinary conference highlighting important and up-to-date clinical and scientific topics in Hirschsprung's disease.
