Which of the following is true of matrix metalloproteinases?
1. They create space for migrating cells during an EMT
2. They create space for new blood vessel formation
3. They release growth factors from the extracellular matrix
4. All of the above
5. None of the above
Homework Answers
Correct answer would be : 4. All of the above.
Reason:Metalloproteins function in the process of cell migration, in angiogenesis( growth of new blood cells) and in release of growth factors from extracellular proteins.

3) Connective tissue types can be categorized by the extracellular matrix that the cells excrete. What types of extracellular substances will you observe during lab? Connective tissues: These tissues vary greatly but consist mainly of cell products. The most common ke cell product is collagen, a tough glycoprotein occurring in fibers so large they must be assembled outside the cell. Connective tissues are also subdivided into different types (e.g., loose, dense, II. fibrous, non-fibrous) but due to their complexity we...
