Summary Introduction

To review:

The role of the autocatalytic nature of pepsin in regulating positive feedback of protein hydrolysis in the stomach.

Introduction:

The stomach is involved in storing large amounts of the food consumed and passing it to the small intestine slowly so that digestion remain slower than ingestion. The walls of the stomach have three types of cells out of that the mucous secreting cells and parietal cells secret HCl (hydrochloric acid), whereas the chief cells secrete pepsinogen.

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?
