  • uterine cavity
  • Gently, the doctor guides the tip of the loaded catheter through the cervix and deposits the fluid containing the embryos into the uterine cavity. (drmalpani.com)
  • Some doctors perform the transfer under ultrasound guidance, to ensure proper placement of the embryos in the uterine cavity. (drmalpani.com)
  • The majority of embryo transfers are currently carried out by cannulating (inserting a hollow tube into) the uterine cavity via the cervix (transcervical transfers). (jrank.org)
  • attachment
  • This prompted Brivanlou and colleagues, including research associates Alessia Deglincerti and Gist Croft, research specialist Lauren Pietila, and fellow Rockefeller scientist Eric Siggia , Viola Ward Brinning and Elbert Calhoun Brinning Professor and head of the Laboratory of Theoretical Condensed Matter Physics , to adapt the technique and create an attachment culture for human embryos. (rockefeller.edu)
  • Aplin's research team concluded that miR-145 influences attachment of the embryo by lowering the level of IGF1R in the uterine lining. (babymed.com)
  • embryonic
  • Understanding human pre-implantation development has important implications for assisted reproductive technology (ART) and for human embryonic stem cell (hESC)-based therapies. (nih.gov)
  • trophoblast
  • Cell boundaries are indicated in white, cells of the inner cell mass (which will give rise to the embryo proper) are in green, and trophoblast cells (which will give rise to extraembryonic tissues) are in purple and magenta. (rockefeller.edu)
  • beneficial
  • The procedure is most beneficial when acupuncture is performed in two sessions - half an hour before, and half an hour after the embryo transfer. (healthcaremagic.com)
  • fluid
  • Additional aspects of successful implantation include bed rest following embryo transfer, the absence of hydrosalpinx (blocked, fluid-filled fallopian tubes) that could lead to washing out of the implanted embryos by intermittent leakage of the hydrosalpingeal fluid. (jrank.org)
  • embryology
  • Through this international and multidisciplinary collaboration combining mouse embryology, human embryology, and physics, we were able to create a system that properly recapitulates what happens during human implantation," says Deglincerti. (rockefeller.edu)
  • Development
  • The complications in roe deer reproduction could be due also to a short defined rutting season (from mid-July to mid-August), long latent period of embryogenesis (between mating in July-August and embryo implantation in November-December), relatively long post-implantation prenatal development (from November-December up to parturition in May-June), which represents potential risk for getting offspring in this species (Raesfield et al. (thefreedictionary.com)
  • This begins the process of development of both the embryo and the placenta that feeds it. (bcm.edu)
  • Implantation is a crucial step in human development. (rockefeller.edu)
  • Human pre-implantation embryo development. (nih.gov)
  • Here, we summarize what is currently known about human pre-implantation embryo development and highlight how further studies of human pre-implantation embryos can be used to improve ART and to fully harness the potential of hESCs for therapeutic goals. (nih.gov)
  • Phase-contrast images of human embryo development from day (d) 0 to day 7. (nih.gov)
  • Imaging human embryo development and predicting developmental potential. (nih.gov)
  • B ) Molecular events and time-lapse images of human embryo development. (nih.gov)
  • Cell fate decisions and their timing in mouse versus human early embryo development. (nih.gov)
  • Professor John Aplin, leader of the study from The University of Manchester's Institute of Human Development in England, says there is only a small window of opportunity for implantation: "This window is open for no more than four days. (babymed.com)
  • quality
  • Embryos are graded according to their appearance and rate of cell-division and good quality embryos are those which have 4-8 cells, of equal size, with clear cytoplasm, and with few fragments. (drmalpani.com)
  • The embryo is selected for quality of viability and other important characteristics. (jrank.org)
  • doctors
  • In some countries, such as the UK, doctors are allowed to replace a maximum of only 2 embryos, to reduce the risk of high-order multiple births. (drmalpani.com)
