Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

In April, researchers in China reported that they had initiated pregnancies in monkeys through a procedure seemingly much like in vitro fertilization (IVF), in which embryos created in a dish were ...

Embryonic morphological development is delayed in live pregnancies ending in miscarriage, according to a prospective cohort study from the Netherlands. Among over 600 singleton pregnancies, those ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is ...
