How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

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 ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

Scientists have developed a new human-based endometrial model to study embryonic implantation in the early stages of pregnancy.

As the climate changes, scientists are concerned about how well plants and animals will adapt to rapid warming. A new University of Vermont study has explored the early embryonic life stage of a ...

According to multiple studies, one in three pregnancies results in miscarriage, and one in 33 babies that are born will have a birth defect, due to the embryo forming incorrectly in the womb. Studying ...

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 ...
