A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

As the climate changes, scientists are concerned about how well plants and animals will adapt to rapid warming. A new ...

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 ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

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 ...

Researchers at the Babraham Institute have ‘listened in’ to the communication between the embryo and the womb lining at the ...

Researchers have created a replica of womb lining or endometrium which allowed them to study the implantation of human embryos — process that signals start of a pregnancy. Described in a paper in the ...

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 ...

Molecular mechanism uncovered in mice by UC Santa Cruz researchers reveals how a father’s diet, stress, and other ...
