Summary Introduction

To determine: The role of cell surface receptors in responding to positional information.

Introduction: Cell surface receptors are cellular proteins which identify and respond to signals by interpreting them. Some cell signals are positional information signals. These signals contain information about the location of the cell with respect to other cells of the body. The cell responds to this positional information through cell division, cell migration, cell differentiation and cell death.
