A Structure of mouse placenta (note: drawings are not up to scale). The different types of cells are shown in detail. B Comparison of 5hmC and TETs levels between mid and late gestation. Green check mark: presence of 5hmC or epigenetic regulator expressed; Red X mark: 5hmC or expression of epigenetic regulator not present; Green arrow: 5hmC or epigenetic regulator levels increased; Red arrow: 5hmC or epigenetic regulator levels decreased
