Summary Introduction

The complex system of the immune system includes special type of cells called lymphocytes. These lymphocytes are immune cells that act against infectious agents like bacteria, virus, and other pathogens. Lymphocytes are classified into two types namely B lymphocytes or B cell, and T lymphocytes or T cell based on the place where they are originated. B cells are synthesized in the bone marrow and T cells in the thymus. There is one more category in lymphocytes that includes natural killer cells.

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.
