Knoepfler is a professor of cell biology and human anatomy at UC Davis School of Medicine. Researchers are racing to engineer highly realistic human embryo models using stem cells in the lab. Some of ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes tied to cholesterol regulation, blood disorders, and early development. One ...

An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic models based on stem cells in the field of reproductive biology. The document, ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique can be used to alter a single gene in human embryonic cells, enabling the ...

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 production ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...

For the first time, researchers have used a genome editing technique called base editing to identify a master gene that is essential for human embryo development. Marking the first application of base ...

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 - ...
