Year 3

Human embryonic stem cells have the potential to proliferate indefinitely in culture while at the same time have the ability to give rise to any cell type present in the human body. As such they represent an important new tool for understanding the underlying causes of disease, for developing new, safer drugs to treat disease and for cell-based therapy for treating a wide range of human diseases and disorders. But the molecular mechanisms regualting human embryonic stem cell growth are still poorly understood.In our studies we have begun to understand how a core group of transcription factors acts to regulate the growth and survival of embryonic stem cells. In adittion we have begun to understand how those factors act through distinct pathways to control the so-called stem cell state. Improvingour understanding of how the stem cell state is regulated will improve our ability to grow stem cells for all of the possible uses of the cells described above. That in turn will accelerate the development of our understanding of human disease and the development of new treatments for human diseases, disorders and injuries.
