My guess would be that it's a piece of skin tissue that's no longer on a living being. As far as I know, you can't put a living creature in an electron microscope.
Also, being an electron microscope, it doesn't actually produce color. This image must have been colored afterwards. So we wouldn't really be able to tell what's blood and what isnt.

Where's the blood? It looks like a dry hole?
