Question
1.
Which of the following is NOT a source for stem cells?
certain adult tissues
early embryos
sperm and eggs
umbilical cord blood
2. Which of the following are potential therapeutic uses of embryonic stem cells?
repair damage to heart muscle after a heart attack
regenerate cells of the immune system
replace neurons after an accident
All of the above are potential therapeutic uses of embryonic stem cells.
3. In the different types of stem cells, which has the most potent to differentiate?
Induced pluripotent cells
Embryo stem cells
Adult stem cells
Fetal stem cells
4. The structure of the chromosomes play important role in the process of cell differentiation.
True
False
certain adult tissues
early embryos
sperm and eggs
umbilical cord blood
Explanation / Answer
1)Answer is C. sperms and eggs is NOT a source for stem cells, as stem cells are an undifferentiated cell of a multicellular organism, which is capable of giving rise to more cells of the same type.
2)Answer is D. All of the above are potential therapeutic uses of embryonic stem cells. Stem cells are having a number of therapeutic uses.
3) Answer is A. Induced pluripotent cells are most potent to differentiate, these are the adult epithelial cells reprogrammed to give rise to pluripotent capabilities with the help of transcription factors. These cells are more potent to differentiate.
4) True. The structure of the chromosomes play an important role in the process of cell differentiation as it is a process by which a less specialized cell(simple zygote) becomes a more specialized cell type (complex system of tissues and cell types) resulting in the development of a multicellular organism.
