the potential uses of stem cells in research and/or medicine

4. Compare and contrast ESCs and iPSCS by considering the following: B) List two ethical considerations for using each cell line.

2. It is often the case that a predisposition to certain forms of cancer is inherited. An example is familial retinoblastoma. What does it mean to have inherited an increased probability of acquiring a certain form of cancer? What subsequent event(s) must occur?

2. A researcher is studying the effects of a novel cancer drug on cell division and comparing the new drug to a traditional chemotherapy drug. The traditional drug causes numerous side effects such as nausea, vomiting, hair loss and susceptibility to infections due to low white blood cell counts. The novel drug is a targeted therapy (specifically targets the abnormal protein in the cancer cell) and is likely to reduce side effects that patients experience when treated with traditional chemotherapy. One group of cancer patients was treated with the novel drug and a second group of cancer patients was treated with the traditional chemotherapy drug. Prior and subsequent to treatment, a mitotic index was obtained from a tumor sample from each patient as well as a bone marrow sample (bone marrow cells give rise to all blood cell types including red blood cells and white blood cells). Since this is a double-blind study (neither the patient nor the researcher knows which patients received…
