The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the embryo model had a yolk sac and a proto-placenta, resembling a state that real ...

The most advanced lab-made human embryo models look like the real thing — they resemble, though don't perfectly replicate, natural embryos about 14 days into development.

Screenshots from the first real-time video of early embryonic development. Fluorescent markers were used to show the movement of the filaments inside embryonic cells.

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation.

Bangkok — Scientists have developed human embryo-like structures without using sperm, an egg or fertilization, offering hope for research on miscarriage and birth defects but also raising fresh ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo.

Four teams have coaxed human stem cells to organize themselves into embryo-like forms. The advance could shed light on fertility.

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

Researchers have captured the most-detailed images yet of human embryos developing in real time, using two common laboratory tools — fluorescent dyes and laser microscopes. The technique ...

A biotech firm wants to create “synthetic” human embryos that would be used to harvest organs in order to facilitate transplants and treat conditions such as infertility, genetic disease, and ...

Now, for the first time, scientists have captured images and video in real time of these early developmental stages, offering exciting insights into the long-standing "mystery" of human development.
