A network of transient domains for breaking symmetry during anterior–posterior axis formation in the porcine embryo

Developmental Dynamics, EarlyView.
Abstract Breaking radial symmetry for anterior–posterior axis formation is one of the key developmental steps of vertebrate gastrulation and is established through a succession of transient domains defined by morphology or gene expression. Three such domains were interpreted recently in the rabbit to be part of a “three‐anchor‐point model” for axis ...

Successful blastocyst production by intracytoplasmic injection of sperm after in vitro maturation of follicular oocytes obtained from immature female squirrel monkeys (Saimiri boliviensis)

The Journal of Reproduction and Development, 2021
Advanced reproductive technologies are being applied for the propagation of squirrel monkeys, to ensure their preservation as a genetic resource and the effective use of their gametes in the future.

Top quality blastocyst formation rates in relation to progesterone levels on the day of oocyte maturation in GnRH antagonist IVF/ICSI cycles

PLoS ONE, 2017
Cycles with progesterone elevation during controlled ovarian stimulation (COS) for IVF/ICSI are commonly managed with a “freeze-all” strategy, due to a well-recognized detrimental effect of high progesterone levels on endometrial receptivity.

Tight Junction Assembly Ensures Maintenance of Pregnancy during Embryogenesis in a Mouse Model

Journal of Animal Reproduction and Biotechnology, 2019
Recent studies showed that tight junctions (TJs) integrity and assembly are required for blastocyst development in mouse and pig models. However, the biological functions of TJs associated with embryo implantation and maintenance of pregnancy were not ...

Transcriptional repression of SOX2 by p53 in cancer cells regulates cell identity and migration

International Journal of Cancer, EarlyView.
What's New? SOX2 is one of the key developmental genes with a reported altered expression in many tumors. The mechanisms underlying SOX2 regulation in cancer, however, remain elusive. This study shows that TP53 transcriptionally regulates SOX2 through binding to its promoter and the SRR2 enhancer.

Uterine glands impact uterine receptivity, luminal fluid homeostasis and blastocyst implantation

Scientific Reports, 2016
Uterine glands are essential for pregnancy in mice and likely humans, because they secrete or transport bioactive substances that regulate uterine receptivity for blastocyst implantation.

The correlation between ANAs and pregnancy loss and their impact on IVF/ICSI‐ET pregnancy outcomes in patients with recurrent pregnancy loss

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To explore the correlation between antinuclear antibodies (ANAs) and pregnancy loss (PL), and to observe its impact on the pregnancy outcomes of in vitro fertilization/intracytoplasmic sperm injection‐embryo transfer (IVF/ICSI‐ET) in recurrent PL (RPL) patients. Methods In this retrospective study, patients first seen at the hospital

Molecular and cellular events during blastocyst implantation in the receptive uterus: clues from mouse models

Journal of reproduction and development, 2017
The success of implantation is an interactive process between the blastocyst and the uterus. Synchronized development of embryos with uterine differentiation to a receptive state is necessary to complete pregnancy.

Efficacy of hormone pre‐treatment before ART to improve reproductive outcomes in infertile women with endometriosis: Network meta‐analysis of randomized controlled trials

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Hormone pre‐treatment is still used before assisted reproductive technique (ART) in endometriotic women, but evidence supporting this recommendation is conflicting. Objectives To evaluate whether hormone pre‐treatment with gonadotropin‐releasing hormone (GnRH) agonists or progestogens could improve fertility in women with ...

Pregnancy via Testicular Sperm Extraction for Anejaculation After Neuroblastoma Surgery

IJU Case Reports, EarlyView.
ABSTRACT Background Surgical treatment of a neuroblastoma, a malignant tumor of the sympathetic nervous system, may result in ejaculatory disorder. There are no reports examining ejaculation disorders after neuroblastoma surgery. Case Presentation The patient was a 31‐year‐old Japanese male who had undergone surgery for neuroblastoma of the abdomen at ...
