What is Wharton's Jelly?Pregnancy
While Wharton’s Jelly sounds like some abstract cooking ingredient, it's actually a gelatinous substance that protects the umbilical cord. Named after Thomas Wharton, whom discovered it in 1656, this jelly-like substance’s function is to provide support for the vein and arteries and also prevents kinking of the umbilical cord during movement of the fetus in the womb.
Wharton’s Jelly reacts to changes in temperature, and at birth it ensures that the blood vessels constrict as the baby’s cord collapses. During delayed cord clamping, healthcare providers are waiting for the cord to stop pulsing, a direct physiological response of Wharton’s Jelly. Eventually, as Wharton’s Jelly hardens, the umbilical cord dries and detaches a few days to a few weeks later.
Wharton’s Jelly is formed from the mesoderm and is rich in stem cells. There are several clinical studies showing that these stem cells can be extracted and cultured to make more stem cells which may be useful in the treatment of many diseases and illnesses. How cool!
