Summary Introduction

To determine:

The analogy for the barrier defenses such as the mucous membrane and skin.

Introduction:

Anatomical barriers include the skin, mucous membrane and hair appendages on the epithelia. It is a type of innate immunity of the body. The innate defense includes the skin, chemicals that degrade the foreign particles and the immune cells found in the blood. It acts on the pathogen in a general form which means it has the same response to every pathogen. The immunity provided by this barrier last for a lifetime, but no form of memory cells is involved

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
