Question
20. In addition to the promise of disease therapies, the uses of stem cells in medical research include the study of how a. diseases develop and progress before phenotypes are visible b. Huntington Disease progresses in its latest stages c. to engineer animal models for human disease d. to harvest multipotent cells from human blastocysts e. to fertilize human eggs in vitro 21. A bone marrow transplant is an example of a stem cell therapy using adult stem cells. a. True b. False 22. Creating transgenic animal models for human disease research allows scientists to study new drugs and treatments in animals such as mice, before giving these drugs to humans. a. True b. False
Explanation / Answer
20. ANS: D. To harvest multipotent cells from human blastocysts.
Explanation:
Stem cell can be generate healthy and functioning specialized cells, which can be replaced diseases or dysfunctional cells.
From multipotent cell few types of cells can be generated. In the condition of diseases the body tissues lost cells is replaced with these cells through various process of disease therapies.
This process is similar to the organ transplantation, but only the treatment consists of transplanting cells instead of organs. So for this process multipotent cells are harvested from human blastocysts.
21. ANS: a. TRUE.
Explanation:
In the diseases of cancer like leukemia, lymphoma and multiple myeloma stem cell transplants are used for treatment.
From 1960 onwards blood stem cells are the only type of adult stem cell are using for cancer treatment. Now a days this procedure is known as bone marrow transplantation.
22. ANS: a. TRUE.
Explanation:
Transgenic studies can give fundamental information on living organisms and human diseases. So these animals are useful as disease model and producers of substances for human welfare.
