The program I'm describing was funded to work with stem cells derived from embryos.

"All the embryos used in CIRM-funded research were donated from IVF clinics. They had either been rejected for implantation and were going to be destroyed, or the couple had decided to stop storing the embryos for future use. The embryos used to create embryonic stem cell lines were already destined to be destroyed."
