This set of Tissue Engineering Questions and Answers for Aptitude test focuses on “Adult Stem Cells”.
1. ______________ are also known as somatic stem cells.
a) Adult stem cells
b) Cancer cells
c) Endometrial cells
d) Epithelial cells
View Answer
Explanation: Adult stem cells are undifferentiated cells, found all through the body after advancement, that increase by cell division to renew dying cells and recover harmed tissues. Otherwise called physical undifferentiated cells, they can be found in adolescent just as grown-up creatures and people, in contrast to embryonic undeveloped cells.
2. Ideally, ____________ should also be clonogenic.
a) red Blood cells
b) adherent cells
c) adult Stem cells
d) carcinoma cells
View Answer
Explanation: In a perfect world, adult stem cells ought to likewise be clonogenic. At the end of the day, a solitary adult stem cell ought to have the option to produce a line of hereditarily indistinguishable cells, which at that point offers ascend to all the fitting, separated cell kinds of the tissue in which it lives.
3. An adult stem cell should also be able to give rise to fully differentiated cells that have mature phenotypes.
a) TRUE
b) FALSE
View Answer
Explanation: An adult stem cell should also be able to give rise to fully differentiated cells that have mature phenotypes, are fully integrated into the tissue, and are capable of specialized functions that are appropriate for the tissue.
4. No one knows the origin of adult stem cells in any mature tissue.
a) TRUE
b) FALSE
View Answer
Explanation: In contrast to embryonic stem cells, which is characterized by their beginning (the inward cell mass of the blastocyst), grown-up undifferentiated organisms share no such conclusive methods for portrayal. Truth be told, nobody knows the starting point of grown-up undifferentiated organisms in any adult tissue. Some have suggested that undifferentiated organisms are by one way or another put aside during fetal improvement and controlled from separating.
5. Adult stem cells are rare.
a) TRUE
b) FALSE
View Answer
Explanation: Grown-up undeveloped cells are uncommon. Their essential capacities are to keep up the enduring state working of a phone—called homeostasis—and, with impediments, to supplant cells that kick the bucket in light of damage or malady. For instance, just an expected 1 of every 10,000 to 15,000 cells in the bone marrow is a hematopoietic (blood-shaping) stem cells (HSC).
