Summary Introduction

To explain: The role of voltage-gated Ca2+ channels in cell-to-cell communication.

Introduction: A synapse is defined as a junction where an axon terminal meets another neuron, muscle cell or gland cell. Neurons communicate with other cells at a synapse. An electrical or chemical signal passes from an axon terminal of the neuron to the plasma membrane of the nearby cell at a synapse. The signals are transferred from the presynaptic cell to the postsynaptic cell. In a chemical synapse, a neurotransmitter is released from an axon terminal. It acts as a signal from the presynaptic cell to the postsynaptic cell.

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.
