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 ...

Around eight days after fertilization, the human embryo implants in the endometrium (the tissue that lines the uterus). After implantation, it enters a developmental phase that is not well understood ...

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 ...

Bangkok — Scientists have developed human embryo-like structures without using sperm, an egg or fertilization, offering hope for research on miscarriage and birth defects but also raising fresh ...

Scientists have grown a scalable new embryo-like model that unshrouds some mysteries of early human development, including blood cell formation, or hematopoiesis—a first for the field. In an article ...

The images show the inside of the cell nucleus at an 8-cell stage (left) and at a later stage (right). Chromosome 19 is shown in red whereas the nucleolus containing the gene-silencing machinery is in ...

Scientists can now create realistic human embryo models in the lab, leading some to suggest that we rethink how we legally define an embryo. When you purchase through links on our site, we may earn an ...

Full view of how bones and joints form in the first trimester uncovers cells and pathways that could help diagnose and treat skeletal conditions in the future. The first 'blueprint' of human skeletal ...

Folic acid, also known as vitamin B9, is an important B-vitamin with many vital functions in the human body. It was discovered in the early 1930s when an English scientist isolated a compound from ...
