A team of reproductive scientists have successfully produced both male and female mice using two different fathers, according to a study published online Wednesday in the journal Biology of Reproduction. According to a December 8 press release from Biology of Reproduction publishers the Society for the Study of Reproduction (SSR), the research "could be a step toward preserving endangered species, improving livestock breeds, and advancing human assisted reproductive technology (ART). It also...

Kinarm Ko and Hans Schöler's team at the Max Planck Institute for Molecular Biomedicine in Mnster have succeeded for the first time in culturing a clearly defined cell type from the testis of adult mice and converting these cells into pluripotent stem cells without introduced genes, viruses or reprogramming proteins. These stem cells have the capacity to generate all types of body tissue. The culture conditions alone were the crucial factor behind the success of the reprogramming...

Researchers have what they think may be a basic recipe for capturing and maintaining indefinitely the most fundamental of embryonic stem cells from essentially any mammal, including cows, pigs and even humans. Two new studies reported in the December 26th issue of the journal Cell, a Cell Press publication, show that a cocktail first demonstrated to work in mice earlier this year, which includes inhibitory chemicals, also can be used to successfully isolate embryonic stem cells from...

Researchers claim they developed a safer way to make powerful stem cells from ordinary skin cells, improving research focused on so-called regenerative medicine.They used a common cold virus to carry transformative genes into ordinary mouse cells and made them look and act like embryonic stem cells.If it can be replicated with human cells, it may offer a safe way to test cell therapy to treat diseases such as sickle cell anemia or Parkinson's, Konrad Hochedlinger of Massachusetts General...

Crossing human eggs with cow eggs to produce an embryo may be well-intentioned according to the scientific community, but those in opposition view the concept as monstrous. In England, at Newcastle University, a team has grown hybrid human-cow embryos for the first time in order to provide research tools for stem-cell based solutions. The embryos were produced after human DNA was injected into eggs from cows' ovaries. These embryos lasted three days prior to dying. According to Dr. Teija...

Britain's Human Fertilization and Embryology Authority (HFEA) gave initial approval to scientists to create human-animal embryos for research. The research will mean the production of human embryos with traces of animal DNA.Experts in the field say the research is vital for finding potential cures for debilitating and life-threatening diseases.Two centers will now be able to start work, with conditions, under one-year research licenses -- King's College London and Newcastle University. The...

PORTLAND, Maine (AP) - Researchers at the University of Southern Maine have identified a "starter hormone" responsible for initiating the process by which caterpillars transform themselves into moths. The researchers also discovered that by manipulating hormone treatments, they could arrest a caterpillar's growth, a finding they suggest will lead to a better understanding of how hormones can control growth in humans. The research by Professor David Champlin and a team of students and...

WASHINGTON -- Actor Michael J. Fox, a Parkinson's disease sufferer, urged President Bush on Wednesday to drop his opposition to expanded embryonic stem cell research as Congress geared up for a pivotal vote for more government spending on the research. "He has an opportunity to do something fantastic for the world," said the actor-activist, calling the legislation a "pro-living bill." The Senate plans to vote on stem cell legislation this month, possibly next week. The House of...

WASHINGTON (Reuters) - Supporters and opponents of human-embryo research wielded politics and science on Tuesday in last-minute battles to push some kind of stem cell legislation through the Senate. Scientists described different kinds of stem-cell technology in Senate testimony, and senators threw as many as six different bills into the mix, each backing a different approach for making human stem cells. "They are just muddying the water and confusing it," said Iowa Senator Tom Harkin, a...

WASHINGTON (Reuters) - A Senate health panel on Wednesdayapproved a bill that would establish a national network toexpand access to umbilical cord blood for research, one ofseveral bills on bioethical issues likely to be debated nextmonth in the fight over embryonic stem cell research. President Bush has vowed to veto any expansion of federallyfunded embryonic stem cell research. But the House easilyapproved such legislation in May, and supporters of the Senatebill predict a strong...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...

Pegasus (the winged horse) Constellation -- Location: Visible in both Hemispheres Coordinates: Right Ascension: 22h; Declination: +20; Source: Greek mythology Pegasus, the winged horse, was the son of Poseidon and Medusa. Medusa had been one of three beautiful sisters. Athena was angered that Medusa met with Poseidon in one of her temples. She changed Medusa into a terrible monster. Zeus kept Pegasus out of the world to placate Athena. Pegasus (and the warrior Chrysaor) sprang from...
