Title
Time-lapse images of mitral cells in the olfactory bulb slice expressing Voltron2
Description
Time-lapse images of Voltron2-expressing mitral cells in mouse olfactory bulb slice at P8. Voltron2, a fast and sensitive chemigenetic voltage indicator, and GCaMP6f were sparsely introduced to mitral/tufted cells by in utero electroporation. The slice in SeeDB-Live was imaged by epifluorescence microscopy. This dataset includes the images of Voltron2_{549}.

(Abstract) Tissue clearing has been widely used for fluorescence imaging of fixed tissues, but its application to live tissues has been limited by toxicity. Here we develop minimally invasive optical clearing media for fluorescence imaging of live mammalian tissues. Light scattering is minimized by adding spherical polymers with low osmolarity to the extracellular medium. A clearing medium containing bovine serum albumin (SeeDB-Live) is compatible with live cells, enabling structural and functional imaging of live tissues, such as spheroids, organoids, acute brain slices and the mouse brains in vivo. SeeDB-Live minimally affects neuronal electrophysiological properties and sensory responses in vivo, and facilitates fluorescence imaging of deep cortical layers in live animals without detectable toxicity to neurons or behavior. We further demonstrate its utility to epifluorescence voltage imaging in acute brain slices and in vivo preparations. Thus, SeeDB-Live expands both the depth and modality range of fluorescence imaging in live mammalian tissues.
