carcinoma in situ: abnormal cells that cluster where they form before spreading into surrounding normal tissue
chromosome: the part of a cell containing genetic information; each human cell contains 46 chromosomes
cloning: a procedure that creates cells identical to each other in every way
Common Rule: The Federal Policy for the Protection of Human Subjects, a policy that requires informed consent from people participating in human-subject research of any kind; it generally does not cover anonymous tissue research on stored tissue
culture medium: material in which cells are grown for research purposes
DNA: deoxyribonucleic acid, the molecules inside cells containing genetic information passed down to future generations
epidermoid carcinomas: cancers found in squamous cells—flat cells that make up the skin's surface
HeLa cells: cancer cells taken from Henrietta Lacks's cervix, now used worldwide for medical research
HIPAA (Health Insurance Portability and Accountability Act): a 2006 law that prevents anyone from publishing or sharing personal medical information without patient consent
HLA markers: human leukocyte antigen molecules on a cell's surface that determine tissue type and immune response
HPV (human papillomavirus): a virus that can cause abnormal cell growth in the form of lesions or growths; some varieties can lead to cervical cancer if left untreated
Pap smear: a screening test for cervical cancer; it involves brushing or scraping a small sample of cells from the cervix
pneumoencephalography: a technique for taking brain images by drilling holes in the skull, draining fluid around the brain, and pumping air in to allow for clearer brain-tissue X-rays; doctors stopped using the technique in the 1970s because it could cause paralysis and permanent brain damage
somatic cell fusion: combining two different types of cells to create new cells with characteristics of both
syphilis: a sexually transmitted disease now treated with antibiotics
telomeres: the ends of a chromosome, which lose a bit of DNA each time a cell divides, eventually resulting in cell death; in cancer cells, telomeres do not get shorter and can grow longer
