(2 points) 42‐101 Final exam May 8, 2012 Name________________________________________________ Unless otherwise stated, there is only one correct answer per question ‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐ Mesenchymal stem cells can differentiate into many tissues including a muscle lineage. From the diagram below, identify the type of stem cell. 9. Mesenchymal stem cell (2 points) A. Multipotent C. Unipotent B. Oligopotent D. Not a stem cell 10. Sattelite cell (2 points) A. Multipotent C. Unipotent B. Oligopotent D. Not a stem cell 11. Myoblast (2 points) A. Multipotent C. Unipotent B. Oligopotent D. Not a stem cell 12. Myotube (2 points) A. Multipotent C. Unipotent B. Oligopotent D. Not a stem cell 13. Mesenchymal stem cells can be isolated from a plug of bone marrow, and 50,000 cells are needed to seed a tissue engineered scaffold. After treating the bone marrow plug, 1,000 cells are isolated. Two days later, there are 3,000 cells. Assuming that the growth rate is proportional to the number of cel...
