This set of Tissue Engineering Multiple Choice Questions & Answers (MCQs) focuses on “Wharton’s Jelly Stem Cells”.
1. _________ is a gelatinous substance within the umbilical cord.
a) Wharton’s jelly
b) Ectodermal layer
c) Endodermal layer
d) Mucosal layer
Explanation: Wharton’s jelly is a coagulated substance inside the umbilical string moreover present in the eyeball’s vitreous humor, all things considered, made up of mucopolysaccharides (hyaluronic corrosive and chondroitin sulfate).
2. Wharton’s jelly is a potential source of ________
a) red blood cells
b) adherent cells
c) adult stem cells
d) carcinoma cells
Explanation: Cells in Wharton’s jelly express a few stem cell genes, including telomerase. They can be extricated, cultured, and instigated to separate into mature cell types, for example, neurons. Wharton’s jelly is, in this manner, a potential wellspring of the adult stem cells (additionally observe the more typical technique for putting away cord blood).
3. Wharton’s jelly may contain some fibroblast and ___________
b) T cells
c) B cells
d) Natural killer cells
Explanation: Wharton’s jelly may contain a few fibroblasts and macrophages. A fibroblast is a sort of natural cell that integrates the extracellular grid and collagen, produces the auxiliary structure (stroma) for creature tissues and assumes a basic job in wound recuperating. Macrophages are a sort of white platelet, of the safe framework, that overwhelms and processes cell flotsam and jetsam, remote substances, microorganisms, malignant growth cells, and whatever else that does not have the kind of proteins explicit to sound body cells on its surface in a procedure called phagocytosis.
4. As a mucous tissue, Wharton’s jelly protects and insulates umbilical blood vessels.
Explanation: As a mucous tissue, it ensures and protects umbilical blood vessels. Wharton’s jam, when presented to temperature changes, breakdown structures inside the umbilical cord and along these lines gives a physiological clamping of the rope (a normal of) 5 minutes after birth.
5. Wharton’s jelly is derived from extra-embryonic ____________
d) mucosal layer
Explanation: Wharton’s jelly is gotten from extra-embryonic mesoderm. Extraembryonic mesoderm lies outside the fetus, related to fetal layer and placenta advancement. This mesoderm is framed at gastrulation alongside the embryonic mesoderm from the proximal side of the crude streak.
