Prostate with Biospy Core Locations (IMAGE) Cold Spring Harbor Laboratory Caption Rendering of the human prostate gland, roughly the size and shape of a walnut, bisected by the urethra. The locations of each of an individual's 13 biopsy cores are indicated. Information obtained via single-cell sequencing from cells sampled from each core indicate the likely location of a cancerous tumor (dotted lines encompassing cores 2, 3 and 6).
