Title: Yayoi Obata: Pioneering Innovations in Germ Cell Research

Introduction

Yayoi Obata is a distinguished inventor based in Tokyo, Japan. She has made significant contributions to the field of reproductive biology, particularly in the differentiation of primordial germ cells. With a total of two patents to her name, her work is at the forefront of scientific innovation.

Latest Patents

Yayoi Obata's latest patents include a culture method for differentiating primordial germ cells into functionally mature oocytes. This invention addresses the challenge of providing a method to differentiate a primordial germ cell into a functional GV stage oocyte through in vitro culture. The method involves producing a secondary follicle by culturing primordial germ cells and supporting cells while eliminating the effects of estrogen. Additionally, it includes steps for partially dissociating cells between the granulosa and thecal cell layers, ultimately leading to the differentiation of the oocyte into a functional GV stage oocyte.

Another notable patent is the method of constructing nucleus-implanted eggs, parthenogenetic embryos, and parthenogenetic mammals. This invention outlines a process for creating a nucleus-implanted egg with two haploid genome sets derived from mammalian ova. The method includes introducing a primitive ovarian follicle egg into a nucleus-deleted germinal vesicle stage egg and developing it to the MII phase through in vitro maturation.
