Sonic hedgehog gene in Embryogenesis?
- Produced at Base of Limbs in Zone of Polarizing activity
- Patterning along Anterior-Posterior axis CNS development
- Mutation can cause Holoprosencephaly
Wnt-7 gene gene in Embryogenesis?
- Produced at Apical Ectodermal ridge Thickened
- Ectoderm at Distal end of each Developing Limb
- Necessary for Proper Organization along Dorsal-Ventral axis
FGF gene in Embryogenesis?
- Produced at Apical Ectodermal ridge
- Stimulates Mitosis of underlying Mesoderm
- -> Lengthening of limbs
Homeobox (HOX) gene in Embryogenesis?
- Segmental organization of Embryo in a Carniocaudal direction
- HOX mutations –> Appendages in Wrong locations
