Your Organs Are Aging On Different Timelines, Study Suggests

By StudyFinds Analysis – StudyFinds –

Blood vessels might already be showing wear and tear by the time an individual turns 35, decades before some other organs start to change. A new study suggests that’s not random. Different tissues appear to follow distinct structural-aging patterns across adulthood, some breaking down early, some late, and some in two distinct waves years apart.

Scientists built a new tool called PathStAR to study tissue structure, the physical arrangement of cells, blood vessels and supporting material, using leftover samples from organ donors. Rather than training a computer to guess someone’s age from a photo, researchers let the images speak for themselves and asked a simple question: when does each tissue’s physical structure change the most? The answer goes against a common assumption: that aging is a slow, steady decline treating every organ the same way.
