The use of fetal cells in science has become quite controversial. There was an interesting moment in an interview between Radio Lab co-host, Jad Abumrad. and scientist Dr. Leonard Hayflick on this topic when we were making the show Mortality. Dr. Hayflick grew millions of cells from one aborted fetus and pioneered the use of fetal cells for research and the creation of vaccines.

In this take, Jad is talking to Dr. Hayflick in his garage where millions of these cells are preserved. Listen above.
