(A) Optical sections parallel to the top dermis surface (corresponding to 0.0 μm) to a depth of 55.0 μm below the top dermis surface. (B) Optical section from 30 μm above the bottom dermis surface. Brightness/contrast enhancement was applied to (B). Note that the thickness of the dermis is on the order of 600 μm. Bar = 200 μm.
