Summary
Nervous system development entails the co-ordinated multiplication of a small number of founder cells to give the millions of cells of the mature nervous system. Each founder generates a many different cell types. Understanding how this is controlled is among the most challenging problems in modern biology. We will show how the development of the two basic cell types (neurons and glia), is controlled in a part of the nervous system that is relatively simple and accessible for manipulation.
Manipulation Of Enteric Neural Stem Cells For Cell Therapy To Treat Enteric Neuropathies

Summary
Cell therapy offers great promise for the treatment of motility disorders due to defects in the nerve cells in the bowel. Patient-derived cells are likely to be the best source of cells, however, patient-derived cells will require manipulation because they are likely to be defective. We will identify manipulations of stem/progenitor cells that increase their efficacy for cell transplantation.
Neurons within the wall of the bowel play an essential role in gut motility. A number of motility disorders are caused by diseased enteric neurons, but there are currently no effective treatments for these diseases. We will use animal models of a pediatric motility disorder to examine whether stem cells implanted into the colon can generate neurons and restore normal motility.

Summary
The intestine has its own nervous system which develops from cells that migrate into the intestine during early development. Sometimes this does not work and part of the bowel has no nerves and cannot function. This is treated now by cutting out this bad bowel and joining the sections of good bowel. But it may be possible to grow new nerves in the bad bowel using stem cells. This project aims to test whether this treatment, which would avoid loss of bowel, is possible.

Summary
Neural crest cells are specialised stem cells that give rise to many tissues and organs during embryonic development. We recently identified an essential role for a regulatory protein in neural crest cells. Our research is aimed at understanding how this protein influences the growth of structures such as the heart and facial skeleton. Understanding these processes underpins the ultimate goal of implementing diagnostic and preventative medicine for highly prevalent congenital birth defects.
Neural Crest Stem Cell Therapy For Absence Of Intestinal Nerves In Hirschsprungs Disease

Summary
Hirschsprung's disease is acommon birth defect caused by failure of nerve cells to get into the colon. This results in intractable often fatal constipation. Current treatment is surgical removal of the affected colon soon after birth but often problems persist. These nerves might be rebuilt using nerve stem cells, but not all stem cells have this capacity. And is not known if this can be achieved after birth: This project will define which stem cell populations to use and in what age of bowel.

Summary
Gastrointestinal motility disorders caused by damage or diseased neurons in the gut wall ("enteric neuropathies) are some of the most clinically challenging conditions to manage because of a lack of effective treatments. Our recent animal studies suggest that cell-based therapies are a real possibility to treat enteric neuropathies. In this project, we will methodically address the outstanding steps that need to be addressed with the aim of moving enteric cell therapies to the clinic.

Summary
Gastrointestinal tract function is controlled by nerves in the intestine. These are missing in a small segment of the colon in the serious birth defect Hirschsprung disease. Current treatment is surgical removal of the affected colon segment, but instead, it may be possible to use nerve stem cells to provide some functional recovery. In particular, we are facing two practical questions: How can we produce enough nerve stem cells? and: How can these nerve stem cells be emplaced in the colon wall?
