Figure Lengend Snippet: Target sectioning – Transition from 3D light sheet to 2D multi-cyclic imaging Sample rehydration in descending ethanol series and PBS (100%, 90%, 70%, 50%, 30%, PBS and PBS) and cryoprotection with 30% sucrose solution (Step 30). Angle correction through angled agarose blocks and embedding in optimal cutting compound (Step 33). Snap freezing with isopentane and liquid nitrogen (Step 34). Iterative feedback loop to verify simulated cutting path with cryosectioning in 10 μm increments (Step 35), navigation through anatomical landmarks and 3D-IF fluorescence signature with stereo/fluorescence microscopy (Step 36) and comparison of optical physical sections versus theoretical optical sections (Step 37). This process is repeated until target plane is reached (feedback loop, Step 35–37). Scale bars: (Verification) 500 µm.
