Developmental Biology, 2000 A lesson learned from modern developmental biology is the striking degree of conservation of strategies and molecules used to program developmental events in species as diverse as insects, birds, amphibians, and mammals. Nonetheless, mammals retain distinctions with regard to the strategies used to protect and nourish their offspring during development,

Microbead Implantation in the Zebrafish Embryo [PDF]
Journal of Visualized Experiments, 2015 The zebrafish has emerged as a valuable genetic model system for the study of developmental biology and disease. Zebrafish share a high degree of genomic conservation, as well as similarities in cellular, molecular, and physiological processes, with other vertebrates including humans.

The evolution of embryo implantation
The International Journal of Developmental Biology, 2014 Embryo implantation varies widely in placental mammals. We review this variation in mammals with a special focus on two features: the depth of implantation and embryonic diapause. We discuss the two major types of implantation depth, superficial and interstitial, and map this character on a well-resolved molecular phylogenetic tree of placental mammals.

Frontiers in Cell and Developmental Biology, 2020 Embryo implantation failure is considered a leading cause of infertility and a significant bottleneck for in vitro fertilization (IVF) treatment. Confirmed factors that lead to implantation failure involve unhealthy embryos, unreceptive endometrium, and ...

Alternative Splicing in Embryo Implantation. [PDF]
Matern Fetal MedAbstract Alternative splicing (AS) is a crucial process that produces functionally distinct proteins from a single gene, depending on the developmental or physiological state of cells in multicellular organisms. It plays a significant role in cellular proliferation, survival, and differentiation, including embryonic development,

Journal of Nanobiotechnology, 2023 Most pregnancy losses worldwide are caused by implantation failure for which there is a lack of effective therapeutics. Extracellular vesicles are considered potential endogenous nanomedicines because of their unique biological functions.

Assessment of Embryo-Induced Transcriptomic Changes in Hamster Uterus Using RNA-Seq
Cellular Physiology and Biochemistry, 2018 Background/Aims: The mouse is widely used as an animal model for studying human embryo implantation. However, the mouse is unique in that both ovarian progesterone and estrogen are critical to implantation, whereas in the majority of species (e.g.

The Complicated Effects of Extracellular Vesicles and Their Cargos on Embryo Implantation
Frontiers in Endocrinology, 2021 As a rate-limiting step in pregnancy, embryo implantation is highly dependent on intercellular communication. Extracellular vesicles (EVs) are newly identified to be important in the course of intercellular communication.
