  text: Most neurons are not replaced during an animal’s lifetime. This nondividing
    state is characterized by extreme longevity and age-dependent decline of key regulatory
    proteins. To study the lifespans of cells and proteins in adult tissues, we combined
    isotope labeling of mice with a hybrid imaging method (MIMS-EM). Using 15N mapping,
    we show that liver and pancreas are composed of cells with vastly different ages,
    many as old as the animal. Strikingly, we also found that a subset of fibroblasts
    and endothelial cells, both known for their replicative potential, are characterized
    by the absence of cell division during adulthood. In addition, we show that the
    primary cilia of beta cells and neurons contains different structural regions
    with vastly different lifespans. Based on these results, we propose that age mosaicism
    across multiple scales is a fundamental principle of adult tissue, cell, and protein
    complex organization.
