The property of Henrietta Lack's cells that was most unusual when they were grown in the laboratory was that THEY CONTINUE TO DIVIDE AND MULTIPLY AFTER DECADES OF CULTURING.
Henrietta Lack's cells refers to the sample of cancerous cells that were extracted from a cancer patient named Henrietta for examination in the laboratory. The cells were cultured in the laboratory and they were used for research purposes. One surprising thing that scientists discovered about the cells is that the cells have the ability to continuously divide and multiply even many years after extracting them from their source.<span />
