Question

A embryonic connective tissue is
A. Wolman’s jelly
B. Wharton’s jelly
C. Wright’s jelly
D. None of the above

Answer 1

Hint: Wharton's jelly (substantia gelatinosa funiculi umbilicalis) may be a gelatinous substance within the duct , largely made from mucopolysaccharides (hyaluronic acid and chondroitin sulfate). It acts as a mucous animal tissue containing some fibroblasts and macrophages, and springs from extraembryonic mesoderm.

Complete answer:
> A unique connective tissue present in the umbilical cord, an embryonic connective tissue also called Wharton's jelly is a unique body fluid. It is an amniotic derived connective tissue.
> As a mucous animal tissue, it's rich in proteoglycans, and protects and insulates umbilical blood vessels.
> On exposure to temperature, Wharton's jelly changes, collapses structures within the duct and thus provides a physiological clamping of the cord for a mean of 5 minutes after birth.
> Cells in Wharton's jelly express several somatic cell genes, including telomerase. they will be extracted, cultured, and induced to differentiate into mature cell types like neurons. Wharton's jelly is therefore a possible source of adult stem cells, often collected from cord blood.
> Wharton's jelly-derived mesenchymal stem cells may have an immunomodulatory effect on lymphocytes, Wharton’s jelly is derived from mesenchymal stem cells.
> During a recent study, Wharton’s jelly tissue transplantation has shown to be ready to reduce traumatic brain injury and should have therapeutic potential.

So, from the above discussion it can be concluded that the correct answer is option B.

Note:
It is named for English physician and anatomist Thomas Wharton (1614–1673) who first described it in his publication Adenographia, or "The Description of the Glands of the whole Body", which was published in 1656 for the first time.
