The Cell That Wouldn't Stop
In 1951, doctors took cells from Henrietta Lacks, a patient with cervical cancer. These cells, known as HeLa cells, became immortal - they continued dividing indefinitely in laboratory conditions. While normal cells have built-in controls that limit their division, cancer cells have lost these controls. Today, HeLa cells are still used in research worldwide, helping scientists understand cancer and develop treatments.
Cancer affects millions of people globally and represents one of biology's most complex challenges - understanding how normal cell division control breaks down.
