Title
Time-lapse images of glomerular layer in the olfactory bulb in vivo expressing Voltron2 after clearing with SeeDB-Live
Description
Time-lapse images of mitral cells expressing Voltron2 in the olfactory bulb of an anesthetized mouse after clearing with SeeDB-Live. Voltron2 was specifically and sparsely expressed in mitral/tufted cells using the Pcdh21-Cre driver and a Cre-dependent adeno-associated virus (AAV) vector, labeled with JF549-HaloTag ligand (Voltron2_{549}). Voltage change in the dendrites of the mitral cell in response to odor stimulation (1% amyl acetate) were imaged. The odor was delivered to a mouse nose for 5 seconds at 1 litter per minute.

(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.
