How does a tiny cluster of cells become an embryo with a head, trunk, and tail? And how do thousands of genes coordinate this development? A new imaging method makes it possible to visualize the ...

A team of scientists has identified an unexpected embryonic "starting point" for several brown-fat depots: a small cell niche around the dorsal aorta. Using a combination of time-controlled genetic ...

Speaking at a recent meeting of the British Pharmacological Society in Brighton, UK, Christine Mummery described how using embryonic stem cells to create human heart cells could b ...

Study finds that large embryo cells divide step by step using a mechanical ratchet system, challenging the textbook idea of a ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

6 core challenges that researchers must consider as the race to create models that are ever closer to real human embryos heats up.

University of Cambridge scientists have used human stem cells to create three-dimensional embryo-like structures that replicate certain aspects of very early human development - including the ...

Embryonic stem cells (ESCs) are found in the inner cell mass of the human blastocyst, an early stage of the developing embryo lasting from the 4 th to 7 th day after fertilization. In normal embryonic ...

Most people have heard of stem cells. They are often described as "miracle" cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...

Jennifer Zenker receives funding from NHMRC and Viertel Foundation. Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in ...
