They are also proven to be essential for normal embryonic development and cell differentiation. One important step during mouse development is the establishment of epigenetic reprogramming which is believed to be vital for normal growth and development, however; the mechanism is still poorly understood. Creating embryo using reproductive biotechnology such as IVM/IVF, ICSI and nuclear transfer may cause abnormal epigenetic pattern. This review summarise the role and the importance of epigenetic in embryonic development as well as reproductive biotechnology from research literature mainly in mouse used as a model for mammalian development.engMahidol UniversityEpigeneticsDevelopmentReproductive BiotechnologyJournal of Applied Animal ScienceReview ArticleFaculty of Veterinary Science Mahidol University
