according to scientists, how much would all the hela cells ever cultured weigh (if we could pile them all on a scale at once)
Thereâs no way of knowing exactly how many of Henriettaâs cells are alive today. One scientist estimates that if you could pile all HeLa cells ever grown onto a scale, theyâd weigh more than 50 million metric tonsâan inconceivable number, given that an individual cell weighs almost nothing.
