“Collagen Fiber Orientations in Bat and Mouse Wing Bones Differ with Age: A Quantitative Polarized Light Microscopy Study”

https://pubmed.ncbi.nlm.nih.gov/38095113

This study compared collagen fiber orientations in wing bones of big brown bats and laboratory mice using quantitative polarized light microscopy, finding that age-related changes in bats differ from mice and are more prominent in the outer cortical bone of bats.
