Detailed visualization of crystal arrangement and organization within iridophores using FIB-SEM

Specialized cells in zebrafish scales called iridophores house microscopic, light-reflecting guanine crystals. This movie shows a detailed visualization of crystal arrangement and organization within iridophores using FIB-SEM. This movie shows a close-up view of the crystal arrays highlighted by pseudo coloring in blue and gray; the cell’s nucleus is pseudo colored red.
