Molecular Signaling Regulating Endometrium–Blastocyst Crosstalk

International Journal of Molecular Sciences, 2019
Implantation of the embryo into the uterine endometrium is one of the most finely-regulated processes that leads to the establishment of a successful pregnancy.

Robust and generalizable embryo selection based on artificial intelligence and time-lapse image sequences [PDF]

, 2021
Assessing and selecting the most viable embryos for transfer is an essential part of in vitro fertilization (IVF). In recent years, several approaches have been made to improve and automate the procedure using artificial intelligence (AI) and deep learning.

Improving Bovine Embryo Development and Quality Using Bovine Oviductal Epithelial Cell-Derived Conditioned Medium (bOEC-CM). [PDF]

Vet Med Sci
The study investigated the effects of bOEC‐CM on bovine in vitro embryo development. CM from Day 3 enhances blastocyst rate and positively affects the ICM and TE in blastocysts and increases the expression of development‐specific genes. bOEC‐CM may serve as a superior supplement during the final five embryo culture days.

A Novel Predictive Model to Estimate the Number of Mature Oocytes Required for Obtaining at Least One Euploid Blastocyst for Transfer in Couples Undergoing in vitro Fertilization/Intracytoplasmic Sperm Injection: The ART Calculator

Frontiers in Endocrinology, 2019
The POSEIDON group (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) has introduced “the ability to retrieve the number of oocytes needed to achieve at least one euploid embryo for transfer” as an intermediate marker of successful ...

Dietary yolk supplementation decreases rates of yolk deposition in Japanese quail

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 63-73, January 1, 2023., 2023
Dietary supplementation with egg yolk decreases the rate of yolk deposition in quail. Quail with high body condition indices deposit yolk more slowly. Abstract Generation of egg yolk by birds requires the synthesis and deposition of large amounts of protein and lipid, and is often accompanied by the incorporation of additional physiological mediators ...

Murine Blastocysts Release Mature MicroRNAs Into Culture Media That Reflect Developmental Status

Frontiers in Genetics, 2021
Extracellular microRNA (miRNA) sequences derived from the pre-implantation embryo have attracted interest for their possible contributions to the ongoing embryonic–uterine milieu, as well as their potential for use as accessible biomarkers indicative of ...

Evolution in reproductive tempo and investment across the Peromyscus radiation

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 339, Issue 1, Page 13-27, January 1, 2023., 2023
In this review, we summarize diversity among Peromyscus species and populations in a number of reproductive traits. including litter size. We examine associations with environmental variation (map, right). We also use a large dataset compiled from lab‐held colonies (violin ploots, right) of Peromyscus to test for species‐ and population‐level ...

Comparison of clinical outcomes following vitrified warmed day 5/6 blastocyst transfers using solid surface methodology with fresh blastocyst transfers

Journal of Human Reproductive Sciences, 2013
Objectives: The literature regarding clinical outcomes following day 5/6 vitrified warmed blastocysts transfer has been conflicting. We decided to evaluate and compare the clinical outcomes following vitrified warmed day 5/6 blastocyst transfer using a ...

How to make a blastocyst [PDF]

Biochemistry and Cell Biology, 1992
Several of the new reproductive technologies have been cultivated from our current understanding of the genetic programming and cellular processes that are involved in the major morphogenetic events of mammalian preimplantation development. Research directed at characterizing the patterns of gene expression during early development has shown that the ...
