Summary Introduction

Introduction:

Autoimmune diseases arise when the body experiences an attackon self-cells and tissues by the immune system. Self-tolerance is achieved by two mechanisms. First being apoptosis (cell death) of cells that recognize self-antigens. Second, development of naive lymphocytes into regulatory T (Treg) cells that are able to recognize antigens but cannot produce the secondary signals. Deficiency of Treg, some genetic component related toMHC (major histocompatibility complex), or any environmental factor including infections are the main causes of autoimmune diseases.

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.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
