Wharton's jelly published in 1656. Wharton's jelly Wharton's jelly ("substantia gelatinea funiculi umbilicalis") is a gelatinous substance within the umbilical cord also present in vitreous humor of the eyeball, largely made up of mucopolysaccharides (hyaluronic acid and chondroitin sulfate). It also contains some fibroblasts and macrophages. It is derived from extra-embryonic mesoderm. As a mucous tissue, it protects and insulates umbilical blood vessels. Wharton's jelly, when exposed to temperature changes, collapses structures within the umbilical cord and thus provides a physiological clamping of the cord (an average of) 5 minutes after birth. Cells in Wharton's jelly express several stem cell genes, including
