Researchers obtain a pure solution of antibodies that bind specifically to the cadherins (linking proteins) of the desmosomes of epithelial cells of a mouse. They then take a culture of these cells, divide it into separate control and experimental tubes, and add antibodies to the experimental tube and an equal volume of water to the control tube. What is the predicted outcome of this experiment? A. Cells in the experimental tube will adhere to each other, but cells in the control tube will not B. Cells in both tubes will adhere to each other C. Cells in neither tube will adhere to each other D. Cells in the control tube will adhere to each other, but cells in the experimental tube will not

3. Briefly describe the process of creating an induced pluripotent stem cell. a. What was the dogma or principle truth that was proven wrong by this process?

3. A recent report shows that a novel cytokine (STC) can increase the abundance of stem cells in mice's bone marrow. Boss K thinks that purified human STC can be injected into donors prior to bone marrow harvest. Worker P managed to express lots of STC in E. Coli and STC is soluble in E. Coli extract. Boss K wants Worker P to make a polyclonal antibody in rabbits and then use the antibody to purify STC in a large quantity for clinical trial. 4. How to quantify and purify bone marrow stem cells which express a stem cell marker, Sca-1 (Stem cell antigen-1) on their cell surface. List or draw the key steps and reagents.

1. Describe the basics of flow cytometry. How is this technology used to sort cells? 2. Describe an experiment demonstrating the utility of cell sorting in biotechnology. 3. How do you think flow cytometry can be used as a medical application? What are some examples where flow cytometry is used in the treatment or diagnosis of specific diseases?
