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 stem cells are unipotent

2.Which of the following statements regarding stem cells is false?

a.Adult stem cells are present in adult tissues.

b.Embryonic stem cells can give rise to all the different specialized cells in the body.

c.Adult, but not embryonic, stem cells can be grown in laboratory culture.

d.Embryonic stem cells can be induced to differentiate.

e.Adult stem cells are partway along the road to differentiation.

Answer #1

Ans-1- The major difference between embryonic and adult is that embryonic stem cells are totipotent means these cells can give rise to any type of the body cells while the adult stem cells are mostly multipotent or maybe pluripotent means they can generate only a few particular types of body cells. So the option D is correct.

Asn-2- Embryonic stem cell lines are available because these cells are easily culturable while there is no efficient method available for culturing the adult stem cells hence the culture of adult stem cells is very difficult while embryonic adult cells can be easily cultured. So the option C (wrong statement) is the correct answer.

    You have a culture of stem cells growing in a flask in a laboratory. You separate the cells into various dishes and cause them to specialize into different types of cells. You find that you can cause the stem cells to specialize into either red blood cells or white blood cells, but you cannot coax themto specialize into muscle cells or nerve cells. Which of the following is a valid conclusion about your line of stem cells, based on this...

    Cloning Human Embryonic Stem Cells Cloning is now possible by inserting a skin cell from a baby into an unfertilized human egg that has had its own DNA removed. This produces a blastocyte (an undifferentiated embry onic cell), which includes stem cells identical to the baby's. With this technique it is possible to make genetically identical embryonic stem cells from any cell in the human body. This would remove the need to harvest these cells from existing embryos. Theoretically these...

This process usually happens though in vitro fertilization and then donated to research with consent of the donor. These cells are useful for research and can be used to “regenerate and repair damaged tissue, some current therapies such as bone marrow transplantation already make use to stem cells and their potential for regeneration of damaged tissues” (Kohl,...
