预览提示词
Transform the uploaded microscopy images into a publication-quality four-panel figure labeled A-D. Preserve the source pixels and biological structures. Align control and treatment fields in two columns, include a merged fluorescence view, add consistent 20 um scale bars, a compact channel-color legend, and a lower-right quantification inset with clearly marked placeholder axes. Use equal crop sizes, neutral margins, restrained typography, and no decorative imagery.
