Question
Which of the following statement(s) is(are) TRUE about induced pluripotent stemcells?(A) They can self-renew(B) They require specific signals to maintain their stemness(C) They cannot be genetically manipulated(D) They can form organoids in vitro
Solution
The statements that are TRUE about induced pluripotent stem cells are:
(A) They can self-renew: This is TRUE. Induced pluripotent stem cells (iPSCs) have the ability to self-renew, meaning they can divide and produce copies of themselves indefinitely.
(B) They require specific signals to maintain their stemness: This is also TRUE. iPSCs need certain signals from their environment to maintain their undifferentiated state, or "stemness". These signals can come from the surrounding cells, the culture medium in which they are grown, or from specific genes that are active within the cells.
(D) They can form organoids in vitro: This is TRUE as well. iPSCs can be coaxed to form organoids, or 3D structures that mimic real organs, in a lab dish. This is a powerful tool for studying organ development and disease.
The statement that is NOT TRUE is:
(C) They cannot be genetically manipulated: This is FALSE. iPSCs can indeed be genetically manipulated. In fact, they are often genetically modified to introduce or remove specific genes, which is a key part of many iPSC-based research studies.

Are induced pluripotent stem (iPS) cells really the ‘ethical’ alternative to embryonic stem (ES) cells? Provide a rationale for your answer.
Both embryonic stem cell (ESC) research and induced pluripotent stem cell research (iPSC) hold promise for medical treatments. However, some religious groups raise ethical concerns about embryonic stem cells. Why might induced pluripotent stem cells be viewed as a more acceptable alternative by these groups?Read Less(a) iPSC research involves adult cells, whereas ESCs are harvested from embryos.(b) iPSC research requires fewer legal restrictions compared to ESC.(c) iPSC research produces more stem cells than ESC research.(d) iPSC research is a more recent discovery, and religious views have not caught up yet.
