Studies from German Primate Center-Leibniz Institute for Primate Research Reveal New Findings on Bone Resorption (A non-invasive measure of bone growth in mammals: Validating urinary CTX-I as a bone resorption marker through long-bone growth...).

A recent study conducted by researchers at the German Primate Center-Leibniz Institute for Primate Research has validated the use of urinary CTX-I as a non-invasive marker for bone resorption in mammals. The study focused on bonobos and found that urinary CTX-I levels showed day-to-day variability, decreased diurnally, and declined with age. Additionally, there was a positive correlation between urinary CTX-I levels and forearm growth velocity in female bonobos. These findings suggest that urinary CTX-I can be used to examine bone growth trajectories in both captive and wild populations. [Extracted from the article]
