Summary Introduction

To determine:

The structure and function of an anastomosis.

Introduction:

Arteries, capillaries, and veins are three types of blood vessels. In the systemic circulation, as the ventricles of the heart contract, arteries carry blood away from the heart to the body. Arteries branch into smaller and smaller vessels until they feed into the capillaries, where gas and nutrient exchange occurs. From the capillaries, veins return blood to the heart.

Explanation of Solution

The site where two or more arteries (or two or more veins) converge to supply the same body region is called an anastomosis. Anastomosis generally happens in the circulatory system of the body and provide alternate blood supply routes to body tissues or organs if one link is blocked or compromised. Veins tend to form many more elastomers as compared to arteries.

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.
