Cancer is thought to arise from adult stem cells because of their limited potency to differentiate.
A. True
B. False
Homework Answers
cancer arises in the cells when the cells are mutated on the proto-oncogenes such that the protein encoded by it becomes constitutively active or hyperactive or due to mutations on tumor suppressor genes such that it the protein product of the tumor suppressor genes becomes inactive.
stem cells in the adult include those which produce blood cells, the cells produced by the stem cells are differentiated to perform particular functions.
Cancer may arise from stem cells, if the stem cells ( embryonic cells ) remains in the body at positions it is not meant to be.
so the given statement is B) False

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...

1. Induced pluripotent stem (iPS) cells ______________________. a. Are created by the expression of key transcription regulators in cells derived from adult tissues so that these cells can differentiate into a variety of cell types. b. Require a supply of donor egg cells, such as embryonic stem cells. c. Can differentiate into a greater variety of adult tissues than embryonic stem cells. d. Are created by nuclear transplantation. 2. The different characteristics of different cell types in a multicellular organism...

"Stem cells are undifferentiated, primitive cells with the ability both to multiply and to differentiate into specific kinds of cells. Stem cells hold the promise of allowing researchers to grow specialized cells or tissue, which could be used to treat injuries or disease (e.g., spinal cord injuries, Parkinson’s disease, Alzheimer’s disease, diabetes, strokes, burns)."

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.

Q10. Scientists are divided over value of embryonic stem cells (ESC) and adult stem cells (ASC). Some of the specific scientific concerns include: A. Lack of directed control of ESCs differentiation, potentially leading to uncontrollable teratomas in murine models B. ASCs plasticity and ability to differentiate into other tissues and cells C. Accessibility of ESCs and ASCs cell lines D. ASC transplantation and tissue rejection E. All of the above Q11. Cloning does NOT involve which of the...
