ATissue collagen
BTissue factor
CTissue cadherin
DTissue connexin
Answer & Solution
Correct answer: B. Tissue factor
1. Blood clotting is given as an example of the matrix at work in cell communication.
2. When the cells lining a blood vessel are damaged they display a protein receptor.
3. That receptor is called tissue factor.
4. Collagen is a structural protein of the matrix rather than a displayed receptor, so it is not the trigger.
5. The displayed receptor is tissue factor.
