Without that consent, this tissue would be discarded as biomedical waste.

Where do stem cells come from?

Embryonic stem cells come from donated excess fertilized eggs created for the in vitro fertilization (IVF) process, tissue that would otherwise be discarded. Induced pluripotent stem cells are generated in a lab, often by manipulating “mature” cells (such as skin or blood cells) to an embryonic-like state through a process called “reprogramming.” Tissue stem cells […]
