Three-dimensional data capture and analysis of intact eye lenses evidences emmetropia-associated changes and strain-dependent differences in epithelial cell organization. Scientific Reports, 10, Article 16898. https://doi.org/10.1038/s41598-020-73625-9

Organ and tissue development are highly coordinated processes; lens growth and functional integration into the eye (emmetropia) is a robust example. An epithelial monolayer covers the anterior hemisphere of the lens, and its organization is the key t...
