Cheek cells are often studied in school laboratory settings because they can be easily obtained through a mouth rinse or simple swab. Yet, though the individual cells appear very simple under the microscope, they each contain the genetic make-up of the entire body. Thus, they are often used for DNA fingerprinting studies, as well as paternity testing. Interestingly, a group of Australian researchers have recently found another use for human cheek cells. They have devised a test that utilizes cheek cells to measure an individual’s proclivity for high blood pressure.
