The basement membrane type IV collagen is a family composed of six genetically distinct but structurally similar polypeptide chains, โฃ1-โฃ6. The โฃ1(IV) and โฃ2(IV) chains are ubiquitous components of all BMs whereas the other four have a restricted tissue distribution. In the present study, we have an
Members of the recently discovered Eph family appear to play important roles in a variety of developmental processes including tissue segmentation, cell migration and axonal guidance. To begin to understand the functions of the EphA subclass of receptors and their corresponding GPIlinked (ephrin-A)
