The role of Fibroblast Growth Factor 8 (FGF8) in embryonic development and organ formation is gaining increased recognition as scientists uncover its wide-ranging influence. FGF8, a powerful signaling ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

Selecting the healthiest embryo is one of the most important steps in in‑vitro fertilization (IVF), yet it remains one of the most uncertain. Roughly 15% of couples worldwide experience infertility, ...
