A leading scientist at UW-Madison praised a ruling Thursday lifting a recent ban on federal funding for embryonic stem cell research but said an ongoing court case still calls the future of the funding into question. “It?s good news; we hope this will allow the research to go on unimpeded,” said Dr. Tim Kamp, director of the university?s Stem Cell and Regenerative Medicine Center. “The challenge is that it?s hard to plan for the future with this on-again, off-again situation.” A federal appeals court permitted federal funding of embryonic stem cell research to proceed while it considers a judge?s ruling last month that had temporarily shut off the funds.
