However, a large number of small follicles with less than 3 mm in diameter, rather than middle follicles, dominantly exist on the surface of ovaries. On the other hand, the developmental competence of the oocytes from small follicles (in meiosis and early development following fertilization) has been known to be much lower than those from middle follicles. We&#8217;re trying to make clear the molecular reasons about differences in the developmental competence and to make effort to improve the ability by various modifications.<\/p>\n<\/div>\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2018\/11\/animal-development-and-reproductive-biotechnology-f02.jpg\" alt=\"\"  class=\"aligncenter\"\/>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"research-box turquoise\">\n<div class=\"wrap\">\n<div class=\"photo clfx\">\n<p><img decoding=\"async\" src=\"http:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2021\/03\/Animal-Development-and-Reproductive-Biotechnology-02.jpg\" alt=\"\"  class=\"aligncenter\"\/><\/p>\n<ul>\n<li>Assoc.

Our laboratory is interested in understanding the mechanisms of oocyte development, maturation and fertilization in mammals. Problems in oocyte quality cause the infertility, and the development of organelles, such as mitochondria and endoplasmic reticulum, is a key determinant for the successful fertilization and subsequent embryonic development. We are using several techniques to address the roles of organelles in oocytes including in vitro maturation, fertilization, genetic manipulation and live cell imaging.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2018\/11\/animal-development-and-reproductive-biotechnology-f03.jpg\" alt=\"\"  class=\"aligncenter\"\/>\n<\/div>\n<div>\n<img decoding=\"async\" src=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2018\/11\/animal-development-and-reproductive-biotechnology-f04.jpg\" alt=\"\"  class=\"aligncenter\"\/><br \/>\n<img decoding=\"async\" src=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2018\/11\/animal-development-and-reproductive-biotechnology-f05.jpg\" alt=\"\"  class=\"aligncenter\"\/>\n<\/div>\n<\/div>\n<p><img decoding=\"async\" src=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-content\/uploads\/2018\/11\/animal-development-and-reproductive-biotechnology-f06.jpg\" alt=\"\"  class=\"aligncenter\"\/><\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Research Area : Animal Development and Reproductive Biotechnology Prof.FUNAHASHI Hiroaki &gt;&gt;&gt; website Basic and applied research on mammalian  &hellip; <a href=\"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/research\/department-of-animal-science\/animal-development-and-reproductive-biotechnology\"> read more&#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":129,"menu_order":2,"comment_status":"closed","ping_status":"closed","template":"research.php","meta":{"footnotes":""},"class_list":["post-322","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/322"}],"collection":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/comments?post=322"}],"version-history":[{"count":7,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/322\/revisions"}],"predecessor-version":[{"id":2047,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/322\/revisions\/2047"}],"up":[{"embeddable":true,"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/pages\/129"}],"wp:attachment":[{"href":"https:\/\/www.gels.okayama-u.ac.jp\/kokusaisyakaizin\/wp-json\/wp\/v2\/media?parent=322"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
