Stem cells derived from patients with disorders, such as these Parkinson’s cells, could foster drug screening to find treatments and also provide researchers a valuable tool to study disease. Europe certainly believes in the promise of stem cells.A joint public-private collaboration between the European Union and Europe’s pharmaceutical industry, called the StemBANCC project, will spend nearly 50 million euros to create 1,500 pluripotent stem cell lines. But the initiative’s goal isn’t to find a stem cell-based cure for diabetes or Alzheimer’s disease. They hope instead that their stem cell lines will prove to be faster and more effective drug screens...
