And a photo!

Cambridge University added this picture to their website review of Betrayed by Nature. It shows human endothelial cells in culture labelled with three different fluorescent molecules. Publishers, unfortunately, aren’t too keen on colour pix – so my assertions in the book about the stunning things you can see down microscopes aren’t backed up by images like this!

For the enthusiast: cell nuclei are blue, the green fibres are actin and a protein called von Willebrand factor (only made in these cells that line blood vessels)  has a red label. The cell at bottom right is on the point of dividing. Photo by Emily Hayes.
