0 Pancreatic Stellate Cells in Chronic Pancreatitis Lu Yang September 2011 Thesis submitted for a degree of Master by Research Faculty of Medicine The University of New South Wales, Sydney, NSW, Australia i Certificate of Originality ‘I hereby declare that this submission is my own work and to the best of my knowledge it contains no materials previously published or written by another person, nor material which to a substantial extent has been accepted for the award of any other degree or diploma at UNSW or any other educational institution, except where due acknowledgement is made in the thesis. Any contribution made to the research by others, with whom I have worked at UNSW or elsewhere, is explicitly acknowledged in the thesis. I also declare that the intellectual content of this thesis is the product of my own work, except to the extent that assistance from others in the project’s design and conception or in style, presentation and linguistic expression is acknowledged.’ Signed……………………………………………………………… ii Acknowledgements I would like to express my gratitude to my masters’ supervisors Professor Minoti Apte, Dr Phoebe Phillips and Professor Jeremy Wilson, for the opportunity to undertake a master project in the field of alcoholic pancreatitis and for their assistance, guidance and support throughout my candidature. Professor Minoti Apte is not only a scientist of superior quality but also a wonderful person who was always positive, patient and possesses great leadership qualities. Dr Phoebe Phillips has been a constant source of inspiration and provided me with precious intellectual and technical advice. Professor Jeremy Wilson, Head of South Western Sydney Clinical School, despite his many commitments, provided invaluable assistance, encourage, advice and support throughout my studies and during the preparation of this thesis. I thank all past and present research staff of the Pancreatic Research Group (A/Professor Ron Pirola, Zhihong Xu, Xuguo Zhang, Eva Fiala-Beer, Jie Liu, Janet Youkhana and Narada Kiriella) for their support and their help with the isolation of pancreatic stellate cells. Thank you to Dr Alain Vonlaufen for his assistance and advice during my masters candidate and his patience in training me with several lab techniques. I would like to thank my parents for all their understanding, encouragement and patience through out my studies. Finally, I would like to offer my husband Jin a special thankyou for his love, understanding and unconditional support during my studies. iii Publications ___________________________________________________________________ Publications in peer reviewed journals 1.
