content: The detail and contrast are due in part to the lighting as well as the technique. Dr. Andrews used cells from the "HeLa" line of cancer cells (originally from a sample of Cervical Cancer cells from (He)nrietta (La)cks). The green color comes from the genetic insertion of Aurora B protein kinase - linked to the jellyfish green fluorescent protein, and the picture was created under fluorescent light. Additionally, deconvolution was also utilized.
