Which stem cells are the only ones routinely used in cell therapy?
Stem cells that are the only ones routinely used in cell therapy
Ans- Hematopoietic stem cells.(HSCs)
This Hematopoietic stem cells are found in bone marrow and umbilical cord blood.
This stem cells are responsible for maintaining the production of all blood cells throughout the life.
Over 30 years, Hematopoietic stem cells therapy has been widely used for the treatment of leukemia and lymphoma.
7. Which of the following are potential barriers to stem cell therapy? a) Injection of cells may cause either inflammation or be rejected by recipient. b) For iPSC, retroviral insertion of transgenes for reprogramming can cause deleterious mutation. c) Not all stem cells in the population may differentiate into the appropriate tissue and due to the self renewal property, could lead to cancer d) There are societal ethical concerns over the source of embryonic stem cells.
Question 3 What is the purpose of Stem Cell Therapy? Use of stem cells to prevent an animal from aging once it reaches maturity Use of stem cells to create an embryo (without using a fertilized egg) Use of stem cells to create a new individual (for example the sheep Dolly) Use of stem cells to fix or replace tissues that have been damaged Use of stem cells to change one type of tissue into another (for example, muscle tissue...
One challenge for clinical use of inducible Pluripotent Stem Cell therapy is: Finding host pluripotent cells Learning which transcription factors to use The necessity of retroviral or plasmid insert of exogenous DNA into host DNA
Stem cell therapies -> requires multiple infusions of stem cells. Why do you think there is a need to have a number of treatments for effective therapy?
1. What is a stem cell line? A. Stem Cells lined up in a row. B. Stem Cells in the lineage. C. A population of Stem Cells grown by scientists. D. A Stem Cell broken down, with it's contents placed in a line. 2. What is an Adult Stem Cell? A. A cell extracted from mature tissue. B. A cell extracted only from children. C. A cell extracted only from adults. D. Both A and C. E. None of the...
The difference between embryonic and adult stem cells is that a.Embryonic stem cells are normally present during development, adult stem cells are only present when gene therapy is used to induce them to form. b.Both adult stem cells and embryonic stem cells can be treated with growth factors to become any tissue type in the body. c.None of the above. d. Embryonic stem cells are pluripotent, adult stem cells might be pluripotent OR multipotent. e.Adult stem cells are multipotent, embryonic...
How could an embryonic stem cell be used to repair a severed spine? A. Embryonic stem cells secrete proteins that repair all other cell types, including nerve cells. B. Embryonic stem cells can cause any other cell type to multiply. C. Embryonic stem cells are primarily involved with neural growth and development. D. Embryonic stem cells can grow into any other cell type, including a nerve cell.
What are the mechanisms of action in stem cells? What effects does stem cells have in the body? What are potential uses of these stem cell compounds? Should stem cells be prescribed/used by Doctors? How is the safety of these molecules?
Induced pluripotent stem cells represent an important therapy for diseases that result in cellular loss (e.g. Alzheimer’s Disease). Why wouldn’t induced pluripotent stem cells be useful for the treatment of cancer?
Which of the following statements regarding embryonic stem (ES) cells are true? A. They can only generate a very limited number of cell types. B. They can theoretically give rise to all types of cells in an organism. C. They are highly specialized. D. They are pluripotent. E. Harvesting them from human embryos raises ethical and political issues.
