Week 3 of pregnancy is a critical stage when the embryo begins to grow rapidly. During this week, cells divide at an ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Retear and failure to heal are significant post-operative complications in rotator cuff repair surgery despite the use of commercially available rotator cuff repair grafts. Advances in tissue ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

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 ...
