Question

What happens and why : when limb mesoderm is grafted under the ectoderm in any region of an early embryo of chick?

Answer 1

During chick limb bud development, limb mesoderm cells are thought to segregate from the somatopleural mesoderm from which they arise. It was suggested that limb mesoderm cells become more cohesive than their surrounding somatopleural mesoderm cells and thus form a tissue with higher surface tension.

Answer 2

Limb Mesoderm

Explanation:

• The limb mesoderm is grafted in the early embryo of the chief so as to help in the proper development of the limb
• In normal chick the embryo develops in three layers which are known as ectoderm endoderm and mesoderm
• Usually develops from the ectodermal thickenings in the embryo of the chick. However artificial development of Limb may occur due to thickening of the mesoderm
• This biotechnological modification is usually done in the mid stage of the development of the early embryo
