- Could you please describe the general appearance, distribution, and abundance of stem cells in an adult mammal? Thank youarrow_forwardBased on the information scientists and doctors have been able to collect, compare embryonic stem cells to induced pluripotent stem cells (iPSCs), then choose which statement below correctly describes these two types of stem cells. a. They are equivalent. b. iPSCs have more potency than embryonic stem cells. c. Embryonic stem cells are far more potent than iPSCs d. Both embryonic stem cells and iPSCs are totipotent.arrow_forwardAs humans age, the rate of cell division _____, which is intended to _______. Select one: a. increases, decrease the risk of cancer b. Decreases, decrease the risk of cancer c. Increases, increase stem cell division d. Decreases, increase stem cell divisionarrow_forward
- Why are scientists so excited about human embryonic and adult stem cells?arrow_forwardPlease explain the difference between Adult Stem Cell and Embryonic Stem Cells.arrow_forwardOne of the differences between embryonic stem cells and adult stem cells is _____. a extracting embryonic stem cells destroys the embryo b embryonic stem cells are multipotent c the immune system does not have the potential to reject embryonic stem cells d extracting adult stem cells destroys the embryoarrow_forward
- Stargardt's disease was one of these that can be treated using embryonic stem cells. Why would scientist chose to use this type of stem cell in treatment of Stargard's? A. There ae not ethical issue concerning their use B. They retain stem cell properties even after specialization C. They are able to differentiate into the required cell type D. They are already specialized for this funtionarrow_forwardNew 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.arrow_forwardWhy are stem cells not more abundant in the human body? I learned that stem cells can proliferate into any kind of cell in the body. These cells can be very beneficial for repairing damaged tissues and replacing dead tissue. So, if stem cells have so many uses and benefits why are they not more abundant in the human body? What are the benefits and risks of an increase of stem cells? Do the benefits outweigh the possible problems? Is an increase in stem cell numbers only worth while when an injury has occurred such as in stem cell therapy? Thank youarrow_forward
- Discuss the principles that govern the presence and maintenance of stem cells both in vivo and in vitro? What is the current status of the technology, and its possible applications? What are the pros and cons of the technology, and how do these issues personally affect people?arrow_forwardWhy is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell? a. As cells develop, signaling pathways can cause some genes to be turned off during development. b. Adult cells have different DNA content than do embryonic stem cells. c. Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells. d. It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.arrow_forwardWhat are some of the ethical issues that arise from using embryonic stem cells?(b) To avoid these issues, scientists use IPSCs. What are the pros and cons to using iPSCs inrelation to embryonic stem cells?arrow_forward
