Figure 6

Model of Dnmt1o and Dnmt1s protein expression during preimplantation development. A. The top row of schematics depicts the pattern of maternal Dnmt1o protein expression seen during preimplantation development. Dnmt1o is localized in the nucleus of blastomeres of 8-cell embryos. Dnmt1o is not found in the pronuclei. B. The middle row of schematics depicts the pattern of maternal Dnmt1s protein expression in the early stages of preimplantation development. Dnmt1s is not found in the pronuclei. C. The bottom row of schematics depicts the pattern of zygotic Dnmt1s protein expression during preimplantation development. Dnmt1s is evident in nuclei of many stages, including in blastomeres of 8-cell embryos.
