A 31 year old African American lady was used to culture cervical cells which were determined to be immortal - most cells have a predetermined death date after a certain number of divisions.

A vial of her cells are sold anywhere from $400 to $1000!  Lab doctors are big pimping on the sale of black cervix cells.  

This amounts to pimping or cervical cell trafficking akin to prostitution which is a transaction to rent outer portion of the female reproductive tract as few if any hobbyists can reach the cervix.  

The cells are nicknamed Hela after her first name Henrietta and last initial "L".
