This study was performed to pursue the optimal condition for the cryopreservation of mouse morulae by a two-step OPS method and to investigate the feasibility of the optimal condition for vitrification of embryos at other developmental stages. First, the mouse morulae were vitrified in OPS using one-step procedure-that is, embryos were vitrified after(More)
Scientists have done extensive research on viruses in the past decades and formulated many theories about their source. One of the theories is that viruses may be derived from a component of host cells that became autonomous. They resemble genes that have acquired the capacity to exist independently of the cell. Some viral sequences are related to portions(More)
