A competing or co-operating cluster or seven decades of combinatory resources? What's behind a prospering biotech valley?

The Stockholm-Uppsala region is claimed to be one of the worlds' most expansive biomedical regions, both when it concerns scientific and business activities. Or, as it was formulated in a special section in Nature, October 2001: p. 6. "A world class scientific & business environment". A common explanation to the growing commercial activities in the Uppsala region has been a critical event within the cluster; the restructuring the pharmaceutical company Pharmacia. However, research focus on how resources are combined results in an almost opposite picture. It is in interaction with stable and healthy industrial and academic units that new projects/companies develop. Furthermore, this interacting seems not to be restricted to a biomedical cluster, but stretches over several different places and industrial areas.
