Embryonic Mediators of Embryo–Uterus Communication, Implantation and Pregnancy

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT Successful reproduction in eutherian mammals requires intimate connections between the embryo and uterus, involving adhesion, attachment and placentation, with or without invasion of the endometrium. The complex dialogue between embryo and uterus involves numerous molecules and pathways.

Effect of Type of Culture Media on B6D2F1 Mice Oogenesis

Journal of Animal Reproduction and Biotechnology, 2016
This study was conducted to evaluate the effects of type of culture media (BM, G2, OS, TCM, and MEM) on B6D2F1 mice oogenesis. In the present study, B6D2F1/CrljOri F1 mice were utilized in order to maximize oogenesis.

Epididymosome‐Supplemented Extender Induces Changes in Morpho‐Functional Traits and microRNA Levels of Post‐Thaw Sperm and Improves Embryo Developmental Potential

Molecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT While molecular signature contributes to sperm quality and fertility potential, sperm may lost key molecules during cryopreservation. Since sperm cells are transcriptionally inert and rely on interactions with epididymosomes (epEVs) to acquire molecules, herein, we investigated the effects of the addition of epEVs to the cryopreservation ...

Computational modelling unveils how epiblast remodelling and positioning rely on trophectoderm morphogenesis during mouse implantation.

PLoS ONE, 2021
Understanding the processes by which the mammalian embryo implants in the maternal uterus is a long-standing challenge in embryology. New insights into this morphogenetic event could be of great importance in helping, for example, to reduce human ...

Revisiting Pluripotency Acquisition: A Unified Framework for Reprogramming Strategies

Development, Growth &Differentiation, Volume 68, Issue 6, August 2026.
ABSTRACT The traditional hierarchical view of totipotent cells generating diverse lineages of terminally differentiated cells was challenged by the discovery of induced pluripotent stem cells (iPSCs). This breakthrough demonstrated that the ectopic expression of four transcription factors, Oct4, Sox2, Klf4, and c‐Myc (OSKM), can reprogram somatic cells

Dietary Supplementation of Rumen‐Inert Fatty Acids and Rumen‐Protected Choline Modulates the Uterine Environment of Pregnant Beef Cows

Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.
This graphical abstract summarizes that dietary supplementation of pregnant beef cows with unsaturated fatty acids and choline can increase (green) the concentration of metabolites in the uterine luminal fluid and alter the endometrial epithelial transcriptome during the peri‐elongation period (upregulation = green and downregulation = red).

Computer‐Assisted Sperm Analysis (CASA) Versus Manual Evaluation and the Clinical Significance of Sperm Hyperactivated Motility

Andrology, Volume 14, Issue 5, Page 1401-1412, July 2026.
ABSTRACT Background Semen analysis remains the first‐line diagnostic test for male infertility, although it is affected by operator subjectivity. Computer‐assisted sperm analysis (CASA) is proposed to improve objectivity; however, its accuracy and clinical relevance remain uncertain.

Abnormal cleavage patterns in equine in vitro‐produced embryos lead to higher early pregnancy loss

Equine Veterinary Journal, Volume 58, Issue 4, Page 970-980, July 2026.
Summary Background Despite significant advances, in vitro production (IVP) of equine embryos continues to lack standardised embryo classification criteria and is associated with increased rates of early pregnancy loss compared with in vivo‐derived blastocysts.

Cell lineage specification and its regulation mechanisms during mammalian preimplantation development

浙江大学学报. 农业与生命科学版, 2018
Preimplantation development refers to the early embryonic development between fertilization and implantation. During this short developmental window (4.5 days of mouse), a series of morphological and developmental changes take place. In morphology, three

Porcine Expanded Potential Stem Cells as a Versatile Platform for Multiplex Genome Editing and Immunophenotyping in Xenotransplantation

Xenotransplantation, Volume 33, Issue 4, July/August 2026.
ABSTRACT Xenotransplantation utilizing pig donors offers a promising solution to organ shortages, but immune incompatibilities across species remain a major challenge. Current reliance on porcine primary fibroblasts for genome editing is limited by low inefficiency in complex gene editing and difficulties in immunophenotyping edited cells.
