Introduction
The adult rudiment, which is an adult organ formed in a part of the larval body in echinoderms, has been attracting interest from embryologists and cell biologists for a long time (Wilt, 2002). In sea urchins, the adult rudiment is formed in the left part of the larval body at the eight-armed pluteus stage, and it contains most of the adult tissues, such as tube feet, spines, and tests. At metamorphosis, larval structures are degraded, and the adult rudiment emerges from inside the larval body. However, the details of rudiment formation, such as cell lineages, cell differentiation, or gene regulatory systems during adult organogenesis, are still ...
