Title of seminar: The validation of a functional, isolated pig bladder model for physiological experimentation


-          Synopsis

Our knowledge of bladder function remains incomplete and experimental approaches such as muscle strip experiments, though central to our current understanding, fail to reproduce the complex network of cell-cell interactions that underpin normal bladder function. Improving our understanding of bladder physiology necessitates the use of whole organ preparations and to date most of this work has been done using bladders from small rodents. Extrapolating findings generated using small laboratory animals to lower urinary tract physiology of large animals and to the clinical context is difficult, and requires careful validation. In order to overcome some of these limitations, the aim of our research has been to develop an experimental model using an isolated whole pig bladder, which could be used to study the integrative physiology of the bladder. Using a pump perfusion system, the viability of an isolated large animal bladder can be maintained for a prolonged period of time even after a limited period of warm and cold ischaemia. This experimental approach can be used to study whole organ function of large animal bladders, and the potential for different routes of drug administration may help discern the relative contribution of different cell types in tissue function.


-          Professional Biography

Dr Bahareh Vahabi is a Senior Lecturer in Physiology at University of the West of England and a Research Fellow at the Bristol Urological Institute/University of Bristol. Dr Vahabihas forged a distinguished academic career combining research and teaching at leading universities and hospitals in the United Kingdom.

Focussing her research interests on the physiological and pharmacological function of the urinary tract, she has collaborated with fellow research scientists to relate her findings to medical disorders such as overactive bladder function and has managed to develop a novel isolated large animal bladder model to investigate the integrative physiology of the bladder.
