Summary Introduction

To explain:

The process of antigenic shift in the evolution of the H1N1 swine flu pandemic strain of influenza virus seen in 2009.

Introduction:

Influenza virus is of three types namely A, B, and C. They belong to the family Orthomyxoviridae. They have a diameter of 80-120nm (nanometer). There are various lipoproteins present on the surface of this virus-like hemagglutinin and neuraminidase. Virus binds to the cell surface receptor and mucus lining coat of the respiratory tract is dissolved leading to penetration of these virus particles inside the cells.

If you transplant trunk neural crest into the cranial neural crest region of a developing embryo, will you see the donor tissue form cartilage? Does the neural crest only give rise to two cells in the developing embryo, and is essential for lamprey to develop their jaw structure? Does a multipotent neural crest cell that is receiving Wnt signals become a Chromaffin cell?
Using quail and chick embryos, quail-specific antibody and fluorescent tissue-specific antibodies, design an experiment where you investigate the tissues the cranial neural crest can give rise to.  What are four derivatives of the cranial neural crest that you expect to see in the resulting chimeric embryos?
Does the neural crest have to undergo epithelial to mesenchymal transition prior to migration through the developing embryo?  Does the neural crest differentiate into different cell types based on their axial position along the anterior and posterior axis?
