Animal embryos go through a series of characteristic developmental stages on their journey from a fertilized egg cell to a functional organism. This biological process is largely genetically ...

The interaction between genetics and tissue environment shapes how individual teeth form in different regions of the jaw. While most experimental studies have focused on mandibular (lower jaw) teeth, ...

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 ...
