Pigs and dogs can bridge gap between mice and humans in developing new therapies
Date:12/16/2008

Human and veterinary medicine could receive a big boost through use of larger animals, especially pigs and dogs, in research, with Europe at the forefront. There is the prospect of bringing drugs to the market more quickly at less cost, as well as accelerating progress in other forms of therapy, notably the use of stem cells in regenerative medicine. The potential in this new field was discussed at a recent workshop organised by the European Science Foundation (ESF), which called for a European pig clinic to facilitate generation and characterisation of models of human disease that would be funded within the EU's Seventh Framework programme, the main source of EU funding for research projects.

The immediate goal in the field is to establish a common standardised way of using animals with clearly defined characteristics (phenotypes), so that results can be compared across Europe. "The workshop showed that there is excellent expertise in individual labs, but the phenotypic tests need to be harmonised and standardised to facilitate comparison of results obtained in different labs," said Angelika Schnieke, one of the workshop's convenors, who holds the chair of Livestock Biotechnology at the Centre of Life Science in Weihenstephan, Germany.

Such standardisation has already been achieved for rodents, particularly the mouse, which is the most widely used animal model at present for human disease research. The extension of such a framework to pigs and dogs will bring great rewards not just for human medicine, but also for treatment of animal diseases. "Large animals offer a link between the classical rodent models and application in the clinic," said Schnieke.

"In view of the close genetic, anatomical and physiological similarities between dog and pig on the one side and human on the other, large animal models are likely to catalyse drug development." As Schnieke added, large animals would also help pursue other therapeutic avenues beyon
