Question

Induction is a major theme in developmental biology as these cell-cell signalling events are essential in coordinating development within the body plan. Induction, for example, allows for simple embryonic structures to give rise to a diversity of structures in adults (e.g., somite) or, allows for different germ layers to collectively give rise to a complex organ (e.g., limb, eye). What is induction (3 pts)? Using specific examples, describe the role of induction in coordinating development (4 pts) and also in generating morphological complexity (8 pts).

This is an essay question that I am answering (about 1 page). I would like to check my answer with someone else. Can someone answer this so I can see if I have covered all the necessary points?

Answer 1

part a) inductive cell-cell signalling. Definition: Signaling at short range between cells of different ancestry and developmental potential that results in one cell or group of cells effecting a developmental change in the other.process by which the presence of one tissue influences the development of others. Certain tissues, especially in very young embryos, apparently have the potential to direct the differentiation of adjacent cells. Absence of the inducing tissue results in lack of or improper development of the induced tissue
