Imaging expanded OTCs
(A) The expansion factor can be calculated by measuring the distance between two orientation points before (left) and after (right) expansion. Scale bar: 100 μm.
(B) Representative pictures of dendritic stretch before (top) and after (bottom) expansion, with GFP in green. Scale bar: 5 μm. Note that the scale bar for expanded pictures corresponds to the physical size of the sample as given directly by the microscope based on the imaging parameters.
