How does aging affect cellular function? The Sabatini Lab uses electron microscopy to study mitochondria—often called the powerhouses of the cell—and visualize how their number, size, and shape change over time.

Each color in this image marks a separate cell, with mitochondria appearing as bounded compartments within. The variety within and across cells presents possible evidence of a wide range of metabolic activities. Comparing this image, taken of a young liver, with similar images of older livers allows researchers to assess possible mitochondrial defects or dysfunctions associated with aging.
