Scientists Have Found That Extracellular Matrix Components May Induce Specific

question 29

Multiple Choice

Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testes. For this to happen there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction?

• A) integrins
• B) collagens
• C) actins
• D) fibronectins
