Researchers in Japan say they have grown a tiny human liver from pluripotent stem cells. If the findings prove accurate, it would be the first time anyone has managed to grow a functional human organ from stem cells produced from human skin.

- Scientists grow sperm in laboratory dish (Telegraph, Jan. 2, 2012):
The development opens up the possibility of infertile men being able to father their own children rather than using donor sperm.
Researchers in Germany and Israel were able to grow mouse sperm from a few cells in a laboratory dish.
In a world first a team headed by Professor Stefan Schlatt, at Muenster University in Germany, were able to grow sperm by using germ cells. These are the cells in testicles that are responsible for sperm production.

- 150 human animal hybrids grown in UK labs: Embryos have been produced secretively for the past three years (Daily Mail, July 23, 2011):
Scientists have created more than 150 human-animal hybrid embryos in British laboratories.
The hybrids have been produced secretively over the past three years by researchers looking into possible cures for a wide range of diseases.
The revelation comes just a day after a committee of scientists warned of a nightmare ‘Planet of the Apes’ scenario in which work on human-animal creations goes too far.
Last night a campaigner against the excesses of medical research said he was disgusted that scientists were ‘dabbling in the grotesque’.
Figures seen by the Daily Mail show that 155 ‘admixed’ embryos, containing both human and animal genetic material, have been created since the introduction of the 2008 Human Fertilisation Embryology Act.
This legalised the creation of a variety of hybrids, including an animal egg fertilised by a human sperm; ‘cybrids’, in which a human nucleus is implanted into an animal cell; and ‘chimeras’, in which human cells are mixed with animal embryos.
Scientists say the techniques can be used to develop embryonic stem cells which can be used to treat a range of incurable illnesses.

- Science with real bite: Full set of teeth grown in the lab (Daily Mail, July 13 2011):
Scientists have grown fully formed teeth from stem cells.
The artificial teeth looked like the real thing, were sensitive to pain and could chew food.
The breakthrough was made on mice but could pave the way for those who lose teeth to decay or injury being able to ‘grow’ replacements.
The researchers harnessed the power of stem cells – ‘master cells’ which have the potential to be used to grow any part of the body – to generate teeth.

Used in yards, farms and parks throughout the world, Roundup has long been a top-selling weed killer. But now researchers have found that one of Roundup’s inert ingredients can kill human cells, particularly embryonic, placental and umbilical cord cells. The new findings intensify a debate about so-called “inerts” – the solvents, preservatives, surfactants and other substances that manufacturers add to pesticides. Nearly 4,000 inert ingredients are approved for use by the U.S. Environmental Protection Agency.

Glyphosate, Roundup’s active ingredient, is the most widely used herbicide in the United States. About 100 million pounds are applied to U.S. farms and lawns every year, according to the EPA.
Until now, most health studies have focused on the safety of glyphosate, rather than the mixture of ingredients found in Roundup. But in the new study, scientists found that Roundup’s inert ingredients amplified the toxic effect on human cells-even at concentrations much more diluted than those used on farms and lawns.
One specific inert ingredient, polyethoxylated tallowamine, or POEA, was more deadly to human embryonic, placental and umbilical cord cells than the herbicide itself – a finding the researchers call “astonishing.”
“This clearly confirms that the [inert ingredients] in Roundup formulations are not inert,” wrote the study authors from France’s University of Caen. “Moreover, the proprietary mixtures available on the market could cause cell damage and even death [at the] residual levels” found on Roundup-treated crops, such as soybeans, alfalfa and corn, or lawns and gardens.
The research team suspects that Roundup might cause pregnancy problems by interfering with hormone production, possibly leading to abnormal fetal development, low birth weights or miscarriages. Continue reading »

Pigs raised under oak and beech trees produce the best ham.
But maybe you want to try the lab ‘Petri dish pork’ instead???
LONDON — Call it pork in a Petri dish — a technique to turn pig stem cells into strips of meat that scientists say could one day offer a green alternative to raising livestock, help alleviate world hunger, and save some pigs their bacon.
Dutch scientists have been growing pork in the laboratory since 2006, and while they admit they haven’t gotten the texture quite right or even tasted the engineered meat, they say the technology promises to have widespread implications for our food supply.
“If we took the stem cells from one pig and multiplied it by a factor of a million, we would need one million fewer pigs to get the same amount of meat,” said Mark Post, a biologist at Maastricht University involved in the In-vitro Meat Consortium, a network of publicly funded Dutch research institutions that is carrying out the experiments.
Post describes the texture of the meat as sort of like scallop, firm but a little squishy and moist. That’s because the lab meat has less protein content than conventional meat.
Several other groups in the U.S., Scandinavia and Japan are also researching ways to make meat in the laboratory, but the Dutch project is the most advanced, said Jason Matheny, who has studied alternatives to conventional meat at the Johns Hopkins Bloomberg School of Public Health in Baltimore and is not involved in the Dutch research.

HONG KONG (Reuters) – Chinese researchers have managed to create powerful stem cells from mouse skin and used these to generate fertile live mouse pups.
They used induced pluripotent skin cells, or iPS cells — cells that have been reprogrammed to look and act like embryonic stem cells. Embryonic stem cells, taken from days-old embryos, have the power to morph into any cell type and, in mice, can be implanted into a mother’s womb to create living mouse pups.
Their experiment, published in Nature, means that it is theoretically possible to clone someone using ordinary connective tissue cells found on the person’s skin, but the experts were quick to distance themselves from such controversy.
“We are confident that tremendous good can come from demonstrating the versatility of reprogrammed cells in mice, and this research will be used to … understand the root causes of disease and lead to viable treatments and cures of human afflictions,” said Fanyi Zeng of the Shanghai Institute of Medical Genetics at Shanghai Jiao Tong University.
“It would not be ethical to attempt to use iPS cells in human reproduction. It is important for science to have ethical boundaries,” she said, adding that their study was “in no way meant as a first step in that direction.”
