On the cover: Like the rare and difficult to cultivate tropical flower Rafflesia arnoldii, the largest flower in the world, so are endothelial progenitor cells extremely rare and difficult to grow. They form one of the largest organs in our bodies: the blood vessels. Now Paprocka and colleagues (in this issue) were successful in generating two stable endothelial progenitor cell lines that provide useful and easy to handle model systems for the study of endothelial differentiation and function.
