A critical component of vitrification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Culture<\/h3>\n\n\n\n<p>The process of supporting the development of fertilized eggs. Specialized culture media, incubators, and instruments play a critical role.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Embryo<\/h3>\n\n\n\n<p>A cluster of cells after fertilization, developing from an early-stage embryo to a blastocyst.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Embryo Transfer<\/h3>\n\n\n\n<p>The procedure of transferring an embryo into the uterus. Kitazato\u2019s embryo transfer catheters are used in this process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Incubator<\/h3>\n\n\n\n<p>An equipment used for embryo culture that maintains constant temperature, CO\u2082, and O\u2082 levels. A stable environment is essential for proper embryo development.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Intracytoplasmic Sperm Injection (ICSI)<\/h3>\n\n\n\n<p>A fertilization technique in which a single sperm is directly injected into an oocyte. The precision of specialized pipettes directly affects treatment outcomes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Laboratory Environment<\/h3>\n\n\n\n<p>Environmental conditions such as temperature, humidity, air conditioning, and VOC control that affect embryo culture.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Media (Culture Media \/ Vitrification Media)<\/h3>\n\n\n\n<p>Products that directly affect embryo development environments and the outcomes of cryopreservation and warming processes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Micro Tools<\/h3>\n\n\n\n<p>Micromachined tools used for ICSI and cellular manipulation. One of Kitazato\u2019s areas of expertise.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Oocyte Retrieval<\/h3>\n\n\n\n<p>A medical procedure to collect oocytes from the ovaries. Dedicated instruments such as Kitazato\u2019s oocyte pick-up needles are used.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Quality Control<\/h3>\n\n\n\n<p>A critical function at Kitazato that minimizes lot-to-lot variation and ensures the reproducibility and safety of reproductive medical products.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Thawing \/ Warming<\/h3>\n\n\n\n<p>The process of warming cryopreserved embryos, oocytes, or sperm for use in fertility treatment.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Traceability<\/h3>\n\n\n\n<p>The management of records tracking reproductive medical products from manufacturing through distribution. A key concept in Kitazato\u2019s quality assurance system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Unmet Medical Needs<\/h3>\n\n\n\n<p>Medical needs for which sufficient treatment options do not yet exist. We contribute to addressing these needs through technological development in the field of reproductive medicine.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Validation<\/h3>\n\n\n\n<p>Activities conducted to verify that manufacturing processes and operations are performed correctly and reproducibly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vitrification<\/h3>\n\n\n\n<p>A cryopreservation method that uses high concentrations of cryoprotectants and ultra-rapid cooling to suppress ice crystal formation and minimize cellular damage.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Assisted Reproductive Technology (ART) A collective term for medical technologies that support pregnancy, incl [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":2522,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"fix\/ir_block_common.php","meta":{"_acf_changed":false,"footnotes":""},"class_list":["post-2999","page","type-page","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/pages\/2999","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/comments?post=2999"}],"version-history":[{"count":1,"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/pages\/2999\/revisions"}],"predecessor-version":[{"id":5060,"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/pages\/2999\/revisions\/5060"}],"up":[{"embeddable":true,"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/pages\/2522"}],"wp:attachment":[{"href":"https:\/\/www.kitazato.co.jp\/en\/wp-json\/wp\/v2\/media?parent=2999"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
