To ask Her Majesty’s Government what evidence the Human Fertilisation and Embryology Authority has received that bona fide trophectoderm stem cells have already been successfully derived and propagated from human embryos; whether any such stem cell lines have been deposited in the UK Stem Cell Bank; and if so, when.

The Human Fertilisation and Embryology Authority has advised that it holds information on the number of stem cell lines derived in each licensed research project and checks for compliance (on inspection) with the requirement for stem cell lines to be deposited in the UK Stem Cell Bank. However, this information does not differentiate between stem cells derived from the inner cell mass and those from trophectoderm.
