Stem Cells

Question 1

What is the first step in creating induced pluripotent stem cells (iPS cells)?

Answer 1

Isolation of somatic cells from a donor

Question 2

Which process is used to reprogram somatic cells into induced pluripotent stem cells?

Answer 2

Reprogramming using four transcription factors is used to induce somatic cells to become pluripotent stem cells capable of differentiating into various cell types.

Question 3

After reprogramming somatic cells into iPS cells, what is the next key step?

Answer 3

Selection of iPS stem cell colonies is performed to identify and isolate colonies of successfully reprogrammed cells.

Question 4

What happens after the successful creation of iPS cells?

Answer 4

Differentiation into target cell type is the final step where iPS cells are induced to differentiate into specific cell types for research or therapeutic applications.

Question 5

What best describes Spermatogonial stem cells?

Answer 5

Unipotent

Question 6

What best describes Haematopoietic stem cells?

Answer 6

Multipotent

Question 7

An isolated cell that is able to produce a fertile adult individual is what?

Answer 7

Totipotent

Question 8

Stem cells that give rise to every cell type in the animal body are what?

Answer 8

Pluripotent

Question 9

How many cells does a blastocyst consist of?

Answer 9
