- 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
- Another model, the random model, proposes that any cell in a malignant tumor has the potential to form a new tumor. Does the cancer stem cell hypothesis contradict this idea?What would happen if Stem Cells do not undergo Cell differentiation?_____________ stem cells are capable of differentiating into nearly all cell types, while _________________ stem cells can only differentiate into a limited number of cell types.
- Suppose you discover a new gene called ABC that contributes to the efficiency of DNA damage repair. You have noticed that cells carrying mutations in this gene stop dividing and go into senescence. Do you think that mutations in this gene can cause cancer? Briefly explain your answer.What kind of daughter cells will result if the "Normal cell" above goes through mitosis? A) two normal cells B) two cancer cells C) two specialized cells D) one cancer cell and one normal cellHow do Cyclins work? a. They are kinases that phosphorylate key proteins at different points in the cell cycle. b. They are transcription factors that regulate the transcription of genes required at different stages of the cell cycle. c. They stop progression of cells through the cell cycle. d. They bind and activate kinases related to progress through the cell cycle.
- How might stem cells be used to repair brain or heart damage, even though these cells do not undergo mitosis?How cancer is genetic diseases, in spite of the fact that most cancers are not inherited?There are anticancer that are used to prevent the formation of spindle fibers. Why do you think this is effective in treating cancer? What might happen if certain phases of the cell cycle do not function well? Make a reflective essay about cell division.
- 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?What are the pros and cons to Embryonic stem cells research in Medical research in this country today?What type of cell division will occur after fertilization to create a baby from the fertilized egg?
