Lighting Up Cells in 3-D

A new microscopy technique called iPALM has been used to reveal structures within cells. Fluorescent labels have been attached to integrins, proteins that cells use to attach to surfaces. The yellow and red regions depict areas where the cell has used integrins to attach to a glass surface. The blue and purple regions are networks of integrins inside a cell.
