A. They are derived from embryonic stem cells.
B. Transcription factors play a key role in their production.
C. When implanted into a mouse blastocyst, they are not able to produce viable offspring.
D. They have never been used in a human clinical trial.
Based on the information scientists and doctors have been able to collect, compare embryonic stem cells to induced pluripotent stem cells (iPSCs), then choose which statement below correctly describes these two types of stem cells.
a. They are equivalent.
b. iPSCs have more potency than embryonic stem cells.
c. Embryonic stem cells are far more potent than iPSCs
d. Both embryonic stem cells and iPSCs are totipotent.
Why is it easier to manipulate embryonic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell?
a.
As cells develop, signaling pathways can cause some genes to be turned off during development.
b.
Adult cells have different DNA content than do embryonic stem cells.
c.
Emybronic stem cells pose less of a threat for organ rejection as do an individual s own adult cells.
d.
It is no easier to manipulate emybronic stem cells to differentiate into various tissues than it is to manipulate a typical adult cell.
