gene (or, more specifically, the equivalent gene in humans) has come up in the proposal by the President's Council on Bioethics, as a solution to the stem cell controversy. According to one of the plans put forth, by deactivating the gene, it would not be possible for a properly organized embryo to form, thus providing stem cells without requiring the destruction of an embryo. Other genes that have been proposed for this purpose include Hnf4, which is required for gastrulation. Interactions CDX2 has been shown to interact with EP300, and PAX6.
