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 ...

A team of researchers in the United States and United Kingdom say they have created the world’s first synthetic human embryo-like structures from stem cells, bypassing the need for eggs and sperm.

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

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 into ...

REHOVOT, Israel, Sept 7 (Reuters) - Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into ...

Researchers reveal that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development. CRCHUM researcher Sophie ...

Scientists denounced the move, arguing that fetal tissue is crucial for understanding human development and diseases.

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Typically, bone marrow research relies heavily on animal models and oversimplified cell cultures in the laboratory. Now, researchers from the Department of Biomedicine at the University of Basel and ...
