Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

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 ...

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 ...

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 ...

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 ...

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 ...

Selecting the healthiest embryo is one of the most important steps in in‑vitro fertilization (IVF), yet it remains one of the ...
