Lattice light-sheet microscopy


Lattice light-sheet microscopy: Imaging molecules to embryos at high spatiotemporal resolution. Science doi: 10.1126/science.1257998
Although fluorescence microscopy provides a crucial window into the physiology of living specimens, many biological processes are too fragile, are too small, or occur too rapidly to see clearly with existing tools.  We crafted ultrathin light sheets from two-dimensional optical lattices that allowed us to image three-dimensional (3D) dynamics for hundreds of volumes, often at subsecond intervals, at the diffraction limit and beyond.  We applied this to systems spanning four orders of magnitude in space and time, including the diffusion of single transcription factor molecules in stem cell spheroids, the dynamic instability of mitotic microtubules, the immunological synapse, neutrophil motility in a 3D matrix, and embryogenesis in Caenorhabditis elegans and Drosophila melanogaster.  The results provide a visceral reminder of the beauty and the complexity of living systems.

今年のノーベル化学賞を受賞したDr. EBのラボから、さらに新しい「lattice light-sheet microscopy」の紹介。エエ感じやなぁ。これは使ってみたい。
