Flashcard 139: Which genes of embryogenesis are produced at the **apical ectodermal ridge** (thickened ectoderm at distal end of each developing limb)?
_____
Answer: FGF genes
Extra: **FGF genes** are produced at the **Apical Ectodermal Ridge (AER)**. They stimulate mitosis of the underlying mesoderm, leading to proximo-distal growth (lengthening) of the limbs.
Contrast this with:
* **Wnt-7a**: Produced at the **dorsal ectoderm**; responsible for dorsal-ventral patterning.
* **Sonic hedgehog (Shh)**: Produced at the **Zone of Polarizing Activity (ZPA)**; responsible for anterior-posterior patterning.
* **Hox genes**: Responsible for segmental organization in a cranial-caudal direction.
