To the editor:
The article also references the U.S. biotech sector's "traditional powers including San Diego, Los Angeles and the Bay Area." Southern California ought to start treating its individual biotech clusters as a united power. San Diego, Orange County and Los Angeles have complementary resources we've only begun to tap. Together, we can be an even more competitive regional force.
