To better understand early pregnancy loss without using actual human embryos, scientists employed stem cells to create models that mimic this stage of development ...

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 ...

In contrast to mammalian early embryos, embryonic cells in fish are transparent and develop synchronously in a uniform, single-cell layer sheet, which makes them significantly easier to track.

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study.

Scientists have created an embryo-like structure using monkey embryonic stem cells for the first time, part of an effort to better understand early human development and organ formation.

Zebrafish have the rare ability to regenerate their heart muscle after major damage, unlike humans. Researchers have now ...

Scientists in China this week say they’ve accomplished a first in bioengineering: creating embryo-like structures from monkey stem cells. The structures were implanted in surrogate female ...

A 6-day-old embryo model from Jacob Hanna’s lab in Israel has structures akin to ones found in human embryos 12 days after fertilization. Those structures include a ball of cells (top, purple ...

A cross-department collaboration headed by researchers at Harvard Medical School and Harvard University has witnessed the moment at which cells in the zebrafish embryo heart start beating in ...

Embryo-like structures have been created from monkey stem cells and implanted into female monkeys, marking the first time this has ever been performed. The new research hopes to push forward our ...

But what about embryo-like structures made from stem cells? These “synthetic embryos” can be made without the direct contribution of egg or sperm cells.

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