Scientists have long observed that embryos of different species within a phylum look quite distinct at early and late ...

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 ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...

Embryos in pregnancies that end in miscarriage take longer to develop in the womb than those in pregnancies that result in live births, according to new research published today in Human Reproduction.

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 ...

Using the fruit fly, scientists have constructed a complete and detailed single-cell map of embryo development. This research will also help scientists pursue questions like how mutations lead to ...

Some newly reported clumps of cells growing in lab dishes have been hailed as the closest things to human embryos that scientists have ever made in the lab. These entities are human embryo models — ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

Fredrik Lanner is in the Department of Clinical Sciences, Intervention and Technology, Karolinska Institutet, Division of Gynecology and Reproduction, Karolinska University Hospital, Stockholm, and ...

(Nanowerk News) Cambridge 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 ...

NEW YORK (Reuters Health) - Women undergoing assisted reproduction may be interested to learn that transfer of a "blastocyst-stage" embryo increases their odds of having a boy. Blastocytes are the ...
