Organs age at different speeds: A blood test might soon tell which ones

AI Summary

Researchers at the Austrian Academy of Sciences and University of Vienna have developed AI-based 'tissue clocks' to estimate biological aging rates of human organs via histological images and blood tests. This method can detect differential ageing speeds among 40 tissue types and offers potential for disease monitoring and early diagnosis.

AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed. By analyzing more than 25,000 tissue samples across 40 tissue types, their study reveals that organs age at different rates throughout life and that these changes can even be detected from blood samples. The findings, published in Nature Medicine, provide a new framework for understanding aging and may open new avenues for disease monitoring and early diagnosis.
