Question
Chapter ST.6, Problem 3DQ
Summary Introduction
To determine: Whether the use of stem cell should be reconsidered when it is known that protein aggregates can spread from cell to cell.
Introduction: Huntington disease (HD) is inherited as an autosomal dominant disorder. It is characterized by adult onset, behavioral changes, uncontrolled movements, cognitive decline, and premature death. This disease is caused by the extended polyQ region of the mutant HTT protein.

- Why 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_forwardExcerpt from "Stem Cells Applications in Regenerative Medicine and Disease Therapeutics" by Ranjeet Mahla (2016)Regenerative medicine... deals with functional restoration of specific tissue and/or organ of the patients suffering with severe injuries or chronic disease conditions, in the state where bodies own regenerative responses do not suffice. Donated tissues and organs cannot meet the transplantation demands of aged and diseased populations that have driven the thrust for search for the alternatives. Stem cells are endorsed with indefinite cell division potential, and can [differentiate] into other types of cells. Stem cells pave foundation for all tissue and organ system of the body and mediates diverse role in disease progression, development, and tissue repair processes in host. 18) Which statement, summarized from the excerpt, best supports the claim that stem cells can be used in regenerative therapeutic technology to treat organ failure or congenital disease for a…arrow_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.
