Yet another set of images for a cover submission, this time for JBC but it was not accepted. I thought the microscopy with glowing edges was pretty nice, but apparently not to the liking of the cover editors.

The outside images look like they might have been plastic sections stained with toluidine blue (hence the little bit of metachromasia in the cartilage), the inside images are identical but photoshop was used to create the glowing edges.
