Instead of a sperm and egg, the starting material was naive stem cells which were reprogrammed to gain the potential to become any type of tissue in the body. Chemicals were then used to coax these ...
In the upper of the picture, the normal embryo goes through a key morphogenetic step during the transition from blastocyst to egg cylinder that epiblast cells marked by red are transformed into a ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...
When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...
Transforming human stem cells into embryo-like structures was previously unthinkable. Yet seemingly overnight, multiple teams published initial results that reach towards this goal. Each team has a ...
Preserving the distinction between research purposes and clinical applications, the Human Fertilisation and Embryology Authority (HFEA), a U.K. regulatory body, has approved the use of CRISPR gene ...
Remnants of ancient viruses survive in human DNA, and without them, we would not form or function properly. LTR5Hs is the newest known group of viral genes that has been found to be essential in the ...
Our basic body plan is determined early during embryonic development by the formation of three body axes. Put simply, they determine where up and down, front and back and right and left are. The ...
