Imagine being able to shrink down to a small enough size to peer into the human body at the single-cell level. Now take a deep breath and plunge into that cell to see all of the ongoing biological processes, including the full complement of molecules and their locations within the cell. This has long been the realm of science fiction, but not for much longer. Recent technological advances now allow us to identify and visualize RNA transcripts, proteins, and other cellular components at the single-cell level. This has led to discoveries about the immune system, brain, and developmental processes and is poised to revolutionize our understanding of the entire human body.
