- Many cell lines used in medical research were originally derived from cancerous tissue. Why are cancer cells often used for developing cell lines?
Step by step
Solved in 2 steps
- HeLa cells are a line of cells grown in laboratory culture that has been used extensively in research. This cell line was originally derived from malignant cervical cancer cells that were removed from a woman named Henrietta Lacks in 1951. They were grown in culture and shipped to research labs around the world where they have been used in many important experiments. Like HeLa cells, many other cell lines were originally taken from cancerous tissue. What are the advantages to using cancer cells for developing cell lines? Why not use normal tissue?What is a disadvantage of adult stem cells over embryonic stem cells?What are the pros and cons to Embryonic stem cells research in Medical research in this country today?
- Why are scientists so excited about human embryonic and adult stem cells?What are stem cells? Which stem cell treatment can form a benign tumor? Please explain how benign tumor can form from the stem cell therapy?Describe the role of cell division in at least one of the following areas of biology: Stem cell research Cell cloning for organ replacement therapies Cancer
- If you were to look at a sample of “normal” cells, what phase of the cell cycle do you think most of the cells would be in? If you were to look at a sample of cancer cells, what phase of the cell cycle do you think most of the cells would be in?Cancer can arise spontaneously, but it can also be induced as a result of environmental factors such as sun exposure, infections, and tobacco smoking. If you were asked to help allocate resources to cancer research, what emphasis would you place on research to find cancer cures, compared to that placed on education about cancer prevention?What separates cancer cells from normal cells? Describe one form of mutation that can increase the risk of a normal cell being cancerous.
- What is the difference between the different kinds of STEM cells?How can cancer arise from stem cells?New treatments for several conditions are being developed using stem cells in medical waste, such as biopsy material, teeth, menstrual blood, umbilical cords, and fatty tissue removed in liposuction. For example, fat samples from injured horses are used to grow stem cells to treat tendon injuries. Explain how the two defining characteristics of stem cells enable them to be used to replace damaged or diseased tissue, so that the new tissue functions as opposed to forming a scar.
