ABSTRACT
Totipotency refers to the ability of a single cell to give rise to all the different cell types in the body. Terminally differentiated germ cells (sperm and oocytes) undergo reprogramming, which results in the acquisition of totipotency in zygotes. Since the 1990s, numerous studies have focused on the mechanisms of totipotency. With the emergence of the concept of epigenetic reprogramming, which is important for the undifferentiated and differentiated states of cells, the epigenomes of germ cells and fertilized oocytes have been thoroughly analyzed. However, in early immunostaining studies, detailed epigenomic information was difficult to obtain. In recent years, the explosive development of next-generation sequencing has made it possible to acquire genome-wide information and the rise of genome editing has facilitated the analysis of knockout mice, which was previously difficult. In addition, live imaging can effectively analyze zygotes and 2-cell embryos, for which the number of samples is limited, and provides biological insights that cannot be obtained by other methods. In this review, the progress of our research using these advanced techniques is traced back from the present to its earliest years.
