The image on the left, selected by Hirst from the Science Photo Library, is
a coloured scanning electron micrograph of a biopsy from the intestine of a child with small bowel cancer.
Michael's image shows COS - 7 cells ectopically expressing the Fcγ - receptor performing phagocytosis on beads opsonised with Immunoglobulin G. His false -
colour scanning electron micrograph shows filopodia and pseudopodia projecting around the beads, which will subsequently be fully engulfed.
