Tissue Engineering Multiple Choice Questions 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
Answer: A
Clarification: Wharton’s jelly is a coagulated substance inse the umbilical string moreover present in the eyeball’s vitreous humor, all things consered, made up of mucopolysacchares (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
Answer: A
Clarification: 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 ___________
A. Macrophages
B. T cells
C. B cells
D. Natural killer cells
Answer: A
Clarification: Wharton’s jelly may contain a few fibroblasts and macrophages. A fibroblast is a sort of natural cell that integrates the extracellular gr 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.
A. TRUE
B. FALSE
Answer: A
Clarification: As a mucous tissue, it ensures and protects umbilical blood vessels. Wharton’s jam, when presented to temperature changes, breakdown structures inse 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 ____________
A. mesoderm
B. ectoderm
C. endoderm
D. mucosal layer
Answer: A
Clarification: Wharton’s jelly is gotten from extra-embryonic mesoderm. Extraembryonic mesoderm lies outse the fetus, related to fetal layer and placenta advancement. This mesoderm is framed at gastrulation alongse the embryonic mesoderm from the proximal se of the crude streak.
