London, March 28 : Researchers at Leiden University in the Netherlands have come up with an artificial version of the buttery coating that protects and nurtures a foetus'''' developing skin.
Joke Bouwstra and Robert Rissman say that their artificial "baby butter" may find a use outside the womb, in speeding up wound healing and treating eczema.
Natural vernix caseosa contains a mixture of fatty compounds that waterproof the foetus. It also contains dead cells called corneocytes, which store large amounts of water and ensure that the foetus does not get dehydrated.
The researchers point out that vernix may also act as a barrier to infections, reports New Scientist magazine.
