Living things on the earth transmit genetic information to next generation. So, life goes on. What is the transmitter? The germ cells. The germ cells are extremely special and fascinating even among all of the various cells in the whole body. For example, they are potentially immortal and totipotent. During development, the germ cells are known to migrate the longest distance along unusual pathways, such as the blood vessels and intestine in the embryo. Thus, I am attracted to their mysterious behaviors during development, and research how they migrate. I am also interested in the nature of stemness and of germness, and the evolution of the germ cell. They always fascinate me.
