Summary
In human tissues, most mature cells develop by differentiation from pluripotent stem cells. As they undergo differentiation, their transcriptional activity changes dramatically. Many of the genetic causes for these changes are unknown, which limits research in the use of stem cells for treating and modelling disease. This proposal addresses this problem with cardiac muscle cell differentiation by utilising recent developments in biotechnology that enables individual cells to be sequenced.

Summary
All digestive functions are controlled by a nerve system in the gut wall, and it works without us thinking about it. This is a huge system rivalling the spinal cord in number of nerve cells. And it has may different types of nerve cells. It originates from a very few cells early in the embryo, about 200 times fewer than the spinal cord. How do the cells manage to divide enough to make this system, and how do they 'know' how to make the right types of nerve cells in the right places in the gut?

Summary
This project seeks to understand how a small number of founder cells can divide and differentiate into the myriad different types of cells that make up the mature nervous system. It uses modern genetic techniques to follow progenitor cells as they mature into mature neurons.
Development Of Techniques To Expand Enteric Neural Crest-stem/progenitor Cells And To Administer Them To The Human Neonatal Colon For Repair Of The Enteric Nervous System Deficiciency In Hirschsprung Disease.

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?
