| Research Abstract |
In pearl culture, a small piece of mantle tissue is implanted into a gonad of a pearl oyster in adjacent to a shell bead that is implanted concomitantly. Then outer epithelial cells of the mantle fragment start to migrate along the surface of the bead, which leads to the formation of follicular structure surrounding the bead and subsequent formation of pearl layers on the sureface of the bead. In this study, techniques for pearl formation by the transplantation of the outer epithelial cells were developped. Moreover, transplantation of the blended outer epithelial cells which produce pearls with different yellowness enabled control of the yellowness of the pearls. These results imply future possibilities of pearl production by blending of different types of outer epithelial cells that can produce pearls with differing superior qualities.
