Scientists are looking for stem cell sources in hybrid cow-human embryos or bones, skin and fat tissue, and the solution could be simpler that ever thought. Menstrual blood could be an unlimited, noncontroversial, easily collectable, and inexpensive source of stem cells, as pointed out by a new research published in ... |

We do not know when genetics will insert cow genes in the breasts of the women, the dream of many men, but the first hybrid cow-human embryos and stem cells have already been obtained by British researchers led by Dr. Lyle Armstrong of Newcastle University. The research was presented to Israel's parliament last ... |

Science fiction medicine becomes increasingly real. There's still more to wait until seeing penises growing from ears and hearts from legs, but a Finnish team has replaced a 65-year-old patient's upper jaw with a bone obtained from stem cells coming from his own fatty tissue and grown between his bowels. "T... |

A cloned Scarlet Johanson may be the dream of any man and a Californian company has just made the first step toward this purpose: for the first time, scientists have achieved cloned human embryos using DNA extracted from adult skin cells, as reported in the Stem Cells journal. "That's an important first step tow... |

Having small breasts can turn into an obsession for many women. Losing them, either totally or partially, is a disaster! And this is exactly what happens in many cases of breast cancer. Scientists have tried to take fat from other body parts (breasts are made mainly of fatty tissue) to build up breasts, but often the... |

Could you lose one hand and grow back another? Cut off your ears and regrow another pair? Humans cannot do this, deer neither, but they shed their antlers annually and regenerate others, even bigger and this could come with some explanations for us. And deer are closer to us than the limb regenerating salamanders."Th... |

In the end, there may be no need to kill human embryos for getting stem cells, as two teams have achieved embryonic stem cells from human skin cells. The newly induced pluripotent cells could turn into various cell types of the human organism. "The advantage of using [such] reprogrammed skin cells is that any cells d... |

Cloning poses a huge ethic debate. That's why scientists have been focusing on various sources for getting stem cells, necessary for technologies of organ replacing. We have witnessed tests made on stem cells coming from skin, fatty tissue, bones, testicles, and now, from an unsuspected source: menstrual blood!T... |

They may not produce eyes that have the color you prefer, but researchers have found a method of generating eyes starting with stem cells. At least eye tissues (like retina) could replace damaged parts in cataract, glaucoma, macular degeneration and other ocular conditions that impair vision, leading even to blindnes... |

Would you like to pig out, not to work and still be thin? Good news: this could happen! A new research made in lab mice which spent 15 minutes daily on a vibrating platform found that they grew 28 % less fatty tissue than the group of control animals.But do not be fooled by waistband-jiggling vibration belts. The pla... |

One step further in turning the "Universal Soldier" into reality. A team at the University of Manchester and UK Center for Tissue Regeneration (UKCTR) led by Dr Paul Kingham has managed to turn fat tissue stem cells into nerve cells, with the potential of growing an artificial nerve that will revive paralyzed limbs a... |

The same factor that makes testicles produce millions of sperms daily can lead to their employment as a source of stem cells in treatments against severe conditions, like Alzheimer's (senile dementia), Parkinson's, stroke, diabetes and certain cancers. A team at the Weill Cornell Medical College has managed... |

Stem cell transplant can save the life of leukemia and lymphoma patients, but this comes with a heavy toll: lowered sexual function. If men are likely to bounce back from this over time, women's sexuality seems to be compromised forever. However, the recovered sexual functions of men or women survivors never rea... |

It's cleat that breasts are rather a sexual 'mark' than having a clear breastfeeding purpose in humans. Because otherwise it's hard to explain 300,000 breast augmentations and reconstructions performed in the US only in 2006, a triple number compared to 1997: any woman wants to feel attractive. Bu... |

400 million years old mushrooms were known to grow as big as trees. But this one has been recently picked up, in a forest, close to a coffee plantation, in Mexico's southernmost state of Chiapas, Southern Border University Center officials said on Tuesday. The white mushroom was 20-kilo (41-lb) heavy and 70 cm (... |

You won't believe it, but there are women born with no vagina! A genetic condition, called Mayer-von Rokitansky-Küster-Hauser syndrome (MRKHS), affecting one in 5000 women, induces the lack of vagina development during embryogenesis. These patients can have a normal uterus, ovaries and external secondary sexual ... |

Breasts represent femininity. Having small breasts can turn into an obsession for many women. You can imagine what losing them means for a woman!

It is clear that stem cells research could boom the medical advance. Currently stem cells are extracted from human embryos, but there is a major ethical issue around this theme: the stem cells' extraction destroys the embryos. In US, this type of research does not receive federal funds. Ian Wilmut, famous for cl... |

Stem cells promise everything: from new hearts to new testes or eyes. Now, researchers have announced major advances in stem cell research: directly reprogramming fetal mouse cells to be indistinguishable from embryonic stem (ES) cells. This way scientists could get cell lines tailored to individual patients without ... |

Stem cells are planned ultimately for treating everything: from new hearts to new testicles. British researchers at the University of Sheffield are now trying to make new eyes. Not exactly eyes, but retinal tissues, a fact that would restore vision to many blind people. A handful of patients with age-related macular ... |

This could satisfy both vegans and meat-eaters: lab grown meat. A Dutch team is trying to grow pork in a lab with the aim of delivering meat for millions without raising and slaughtering animals."We're trying to make meat without having to kill animals," said Bernard Roelen, a veterinary science professor at Utr... |

After four years of research, researchers have discovered a way to engineer adult stem cells from human umbilical cord blood to synthesize insulin. This could lead to a revolutionary treatment against diabetes. "This discovery tells us that we have the potential to produce insulin from adult stem cells to help people... |

How big can a mushroom be? A few tens of pounds and with a 2-3 ft diameter? That's small, compared to the largest one that ever existed: as big as a tree! A team at the University of Chicago and the National Museum of Natural History in Washington, D.C., has come with conclusive evidence that one of the weirdes... |

Men, beware!The prospect of female-only conception is getting closer, leaving aside the science fiction movies. Soon, women could produce sperm of their own, a technology that could permit lesbian couples to deliver their own biological offspring. After scientists managed to produce predecessors of sperm cells from m... |

F***ed to the bone could get another meaning as German researchers have successfully achieved immature sperm cells from human bone marrow stem cells. If they can develop to sperm cells, within five years we could have a breakthrough fertility treatment. The mixed team from the Universities of Göttingen and Münster an... |

Scientists working on muscle stem cells realized that all of the one... |

Vertebrates compass all the animals with backbone, from fishes to mammals and birds. But the first vertebrates originated in more primitive invertebrates. From living species, our closest invertebrate relative is the humble sea squirt, which lives attached to the sea bottom, feeding by filtering just like the clams d... |

Statistics show that couple infertility is due equally to men as to women. Male sterility is triggered by impairment in the multiplication and development of the germ cells (that generate sperm cells) or of their supporting tissues. A new investigation pointed out that bone marrow stem cells could be employed in trea... |
