ESTOOLS, a Framework 6 Integrated Project, aimed to develop the tools and knowledge required for application of human embryonic stem (ES) cells in industry and medicine. It was the largest consortium of researchers studying human ES cells in Europe. The project teamed up 21 research groups, bringing together more than 150 scientists in 10 countries. It was the first EU-funded project focused entirely on human embryonic stem cells.  ESTOOLS completed its 4 years of activity in July 2010.
