A population of stem cells that are capable of differentiating into endothelial and smooth muscle cells has been identified, offering improved prospects for vascular tissue engineering.
Stem cell research, xenotransplantation and somatic and germ line gene therapy are examples of emerging technologies that, if successful, will forever change the way we live. But how well does the public understand the benefits and risks of these technologies, and whose responsibility is it to communicate them? Here, Erik Millstone and Patrick van Zwanenberg of the University of Sussex, UK, discuss whether science is suffering because of a lack of transparency in presenting scientific information to its main consumer group—the general public.
