The 14-day limit on scientific study of children conceived in vitro is already abhorrent, and any attempt to extend it should ...

Researchers who study developing human embryos have long limited their experimentation to lab embryos that are no more than 14 days into development. Some scientists are now pushing that boundary.

Scientists have created synthetic blobs that resemble a 14-day-old human embryo for the first time, meaning they can study embryo development beyond a particularly tricky period of pregnancy ...

Jacob Hanna, who led a successful mouse "embryo" experiment, wants to recreate it with human cells but other experts say much more research is needed.

Four teams have coaxed human stem cells to organize themselves into embryo-like forms. The advance could shed light on fertility. By Carl Zimmer In its first week, a fertilized human egg develops ...

Stem cell biologist Jacob Hanna, a member of the 2024 #STATUSList, predicts human embryo models could pave the way to organ transplants.

But mouse embryos also implant into the womb before these early embryonic stages, so they have the same issues with accessibility as human embryos when it comes to live imaging.

This week, research published in the journal Nature detailed a model of a 14-day old human embryo created without using sperm or eggs. The hope is to shine a light into a previously unavailable window ...

A groundbreaking IVF trial has raised hope that women with genetic mutations in their own DNA could one day have children without passing on deadly diseases.

Scientists have succeeded in doing an end run around eggs and sperm to create an embryo with human components out of stem cells, researchers revealed at a conference Wednesday. The synthetic versio… ...
