There are 30 gene-therapy development companies in the Philadelphia area that have raised well over $1 billion in invested capital, and together employ more than 3,000 people. And that's not counting the principal scientists, doctors, and techs who cooperate with them at labs at the University of Pennsylvania, Jefferson, Children's Hospital of Philadelphia, and other teaching hospitals.

Penn was a cradle of gene-therapy experiments in the 1990s, and recent Food and Drug Administration approvals for commercial applications have attracted a flood of investors backing projects developed by faculty and staff. Penn trustees' vote to invest $50 million of university funds in faculty companies in April sparked "over $10 in co-investment for every dollar they invest," said Richard W. Vague, the marketing mogul-turned-investor and philanthropist, who endowed pioneering cellular immunologist and leukemia-fighter Carl June's faculty seat at Penn's Perelman School of Medicine.

The list shows how this region is poised to benefit as treatments advance to market and enrich their owners or are bought up by larger biopharma companies.

Many of the firms here are new companies founded in the last few years, backed by a wave of investors from the big biotech capital centers of Massachusetts, California, and China, as well as Penn and a handful of local capitalists. Other firms on the list date to Philadelphia's long history as a drug center and have adapted to new gene-therapy markets and technologies.
