Worked Example: Identifying Embryonic fields For CSIR NET
Embryonic fields are required in the development of various body parts, including limbs. A key question in developmental biology is: What is the embryonic field responsible for the development of the forelimb bud? This is a specific example.
The zone of polarizing activity (ZPA) and progress zone (PZ)are two critical regions in limb development. The ZPA, located in the posterior limb bud, expresses SHH (Sonic Hedgehog)and anterior-posterior patterning; the PZ, located in the distal limb bud, is responsible for proximal-distal patterning. These processes are interrelated.
Signaling molecules, such as FGF (Fibroblast Growth Factor) and Wnt, also play essential roles in limb field patterning. FGF signaling from the apical ectodermal ridge (AER) promotes limb outgrowth, while Wnt/ฮฒ-catenin signaling regulates limb bud initiation. Understanding Embryonic fields For CSIR NET helps in grasping these concepts; it is essential for exams.
Disruption of embryonic fields can lead to limb abnormalities. For example, ectopic expression of SHH in the anterior limb bud can result in polydactyly (extra digits).
