The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

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 ...

Stem cells are precursors of a variety of different cells: They can turn into anything from blood to bone to muscle. Human blood stem cells, known as hematopoietic stem cells, are the forerunners of ...

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 ...

The team observed the emergence of the three-dimensional embryo-like structures under a microscope in the lab. These started producing blood (seen here in red) after around two weeks of development - ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly. Two of the first physical structures to form in the embryo are ...

A stem-cell-based monkey embryo model that self-organizes into a comprehensive body plan could lead the way to more-sophisticated models of early human development. Xiangyu Kong is in the Department ...

LONDON — Scientists have achieved a major milestone in recreating human tissue development in the lab, successfully generating the notochord — a defining feature of vertebrates that acts like a ...
