How are HeLa cells used today?
Scientists discover that HeLa cells are found to be an effective tool for growing large amounts of poliovirus, the cause of Poliomyelitis, or polio disease. … HeLa cells are used by scientists to develop a cancer research method that tests whether a cell line is cancerous or not.
