ACutFIG 2E&F: Atomic Force Microscopy (AFM) images of young and old C. elegans.

E. AFM cuticle topography images of C. elegans cuticle at day 1, 5, 12 and 19 of adulthood. Topographical images show a decline in cuticle integrity with age as indicated by an increase in roughness with breaks and cavities appearing in older animals.
F. 3-D topographical images show a flattening of the annuli furrow structure when old, 19 day C. elegans are compared to young, 1 day animals (Image source: Essmann et al., 2020; figure is modified from published version Nat Commun 2020 11, 1043 https://doi.org/10.1038/s41467-020-14785-0.)
