Amid court challenges from groups opposed to the state effort, private donors have contributed more than $100 million in recent years to prop up the new stem-cell research agency, the California Institute for Regenerative Medicine, as well as research programs at state universities, according to a tally by The Wall Street Journal. Among the donors are Ray Dolby, the founder and chairman of Dolby Laboratories Inc., who has devoted $21 million to stem-cell-research programs in the past two years. Los Angeles real-estate developer Eli Broad has given at least $27 million. Venture capitalist John Doerr, bond-fund manager Bill Gross, and Qualcomm Inc. founder Irwin Jacobs have also been major contributors. Story in The Wall Street Journal (sub. req.)
