Title: Using baby foreskins to improve women's cosmetics

A research organization is growing human skin in the hope of using it to trial cosmetics and medicines, reducing the need for animal testing. The synthetic skin is made using cells from infant foreskins.

The idea of a "skin factory" may sound sinister, but that is exactly what scientists at the Fraunhofer Institute in Stuttgart have created. Their so-called Hautfabrik grows tiny swatches of skin - not for skin grafts, but for testing consumer products.

The renowned institute is presenting their ground-breaking invention as an affordable and sustainable alternative to animal testing, which many consider unnecessarily cruel.

The skin factory is a machine measuring seven metres long, three metres high and three metres deep, sealed and heated to 37 degrees Celsius – the same temperature as inside people.

The machine is fitted with 500 boards, each with 24 tissue cultures growing on it in little tube formations. In each tube, extremely thin skin samples grow from cells, which robotic hands have painstakingly extracted from foreskins donated to the project. Scientists use enzymes to detach the very top layer of cells from the skin, along with connective tissue and pigment cells.

The foreskin used for the process is only taken from boys up to the age of four. “The older skin is, the worse the cells function,” explained Andreas Traube, an engineer at the institute's department of production technology and automation.

“It is also important that the cells we use are coming from a uniform source," said Traube. "This avoids discrepancies in the production of the new skin."

The equipment developed by the Fraunhofer team can extract between three to 10 million cells from a single foreskin. In the incubator these cells then multiply hundreds of times.

The brand new skin cells are mixed with collagen and connective tissue, which then becomes ‘proper’ skin, measuring up to five millimetres in thickness. The whole process can take up to six weeks, but according to Traube, “We can’t use the machine to speed up the process; biology needs time to take its course.”

In a single month, the machine can produce around 5,000 skin samples. For now, these delicate creations remain untouched as the process is still being authorized by European authorities, who are examining the growths to see whether they are suitable to be used in testing.

But the process has been given the nod of approval by some key members of the Association of Research-based Pharmaceutical Companies (VFA).

“I think the idea is a good one,” said Rolf Hömke, VFA spokesman. “I believe cells from artificially cultivated skin are indeed comparable with real skin.”

“I do think it might take a few years to get up and running though,” warned Hömke. “There are complicated international safety standards, these procedures can’t just be changed overnight.”

At the moment only very small skin samples are being created. “It’s logical that we’d want to take the operation to a bigger scale,” said Traube.

He added that possible future applications for products from the Hautfabrik could be research into cancer, pigmentation diseases, allergic reactions and fungal infections.

The next step for the company is a little smaller though, as their sights are set on synthesizing a human cornea.

Not a new idea. Foreskins are about the closest the medical field can come to stem cells without venturing into legal problems and extremely high expenses. My sister-in-law recently had a stubborn wound on her foot healed by having it stuffed with (medically processed - sterilized and mushed) foreskins. It was so expensive that I said we should have been invited to the circumcisions.

Cord blood drawn off at delivery is a source of stem cells too. Every baby born in America has at least 1 vial of cord blood drawn off at delivery. Wonder if it will ever be used to DNA ID Americans from birth.

The relationship between morality and liberty is a directly proportional one.

"If you love wealth more than liberty, the tranquility of servitude better than the animating contest of freedom, depart from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hand that feeds you. May your chains rest lightly upon you and may posterity forget that you were our countrymen.”

—Samuel Adams

Can they grow lampshades?? I'm just askin'......

“With the exception of Whites, the rule among the peoples of the world, whether residing in their homelands or settled in Western democracies, is ethnocentrism and moral particularism: they stick together and good means what is good for their ethnic group."

I'm not sure. Parents can sign up for a "Cord Blood Bank" and donate the blood for its stem cells. But, even in training in the 80s, drawing the cord blood was the first thing I did after clamping and cutting the cord. I know hospitals kept cord blood at least for a while, but not how they disposed of it.
