These mutant mice may be useful in monitoring the Cre expression in living tissues, and tracing the lineage of
such cells in
embryos,
young, and adult mice at desired time points.
But MPs including Gordon Brown and David Cameron, who both have
young children with severe medical conditions, agreed on a free vote that the benefits of stem cell research using
embryos were
such that experiments, including the use of human admixed
embryos, should be allowed.
