Stem cell research holds great promise for the treatment of millions of Americans with debilitating and possibly fatal diseases. Current legislation and guidelines, however, continue to limit researchers' endeavors in unlocking the potential breakthroughs that stem cell research can provide. To address this concern, today The Endocrine Society issued a Position Statement (http://www.endo-society.org/advocacy/policy) calling for an increase in NIH funding for stem cell research as well as...

Adult eyes cells can be transformed into pluripotent stem cells without introducing foreign genetic material Scientists have overcome a key barrier to the clinical use of stem cells with a technique which transforms regular body cells into artificial stem cells without the need for introducing foreign genetic materials, which could be potentially harmful. The research, published in Stem Cells, suggests that cells taken from a patient's eye can be "reprogrammed" to replace or restore cells...

Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine. "Our results suggest that small forces may indeed play critical roles in inducing strong biological responses in embryonic stem cells, and in shaping embryos during their early development," said Ning...

A team of Michigan State University researchers has developed a new, more efficient way of cloning zebra fish, a breakthrough that could have implications for human health research. The work of the MSU researchers, detailed in the recent issue of the journal Nature Methods, is important because zebra fish, small striped fish common to many aquariums, are quickly becoming the animal of choice for many researchers. "After the mouse, it is the most commonly used vertebrate in genetic studies,"...

San Antonio and Honolulu researchers make important discoveries about point mutation rates in cloned mouse fetusesSan Antonio "¦ Germ cells, the cells which give rise to a mammal's sperm or eggs, exhibit a five to ten-fold lower rate of spontaneous point mutations than adult somatic cells, which give rise to the body's remaining cell types, tissues and organs. Despite their comparatively higher mutation rates, however, adult somatic cells are used as the donor cells in a cloning...

According to a report appearing in the journal Cloning and Stem Cells, animal eggs cannot be used to create human clones.Dr. Robert Lanza of Advanced Cell Technology and his colleagues failed in an effort to use mouse, cow, and rabbit eggs to produce workable human embryos.Lanza reported that his team was able to make a viable embryo using human cells, and believes that human cloning appears to be possible in principle.Researchers in the past have tried using animal eggs as a source for...

NEW ROCHELLE, N.Y., Feb. 2 /PRNewswire/ -- Since the cloning of Dolly the Sheep over a decade ago, somatic cell nuclear transfer (SCNT) has been considered a promising way to generate human, patient-specific stem cells for therapeutic applications. The shortage of human donor eggs has led to efforts to substitute animal oocytes. However, a new study published online ahead of print in the Volume 11, Number 2, 2009 issue of Cloning and Stem Cells, a peer-reviewed journal published by Mary Ann...

New study questions ability of human-animal hybrids to generate stem cells WORCESTER, Mass., Feb. 2 /PRNewswire-FirstCall/ -- Advanced Cell Technology, Inc. (OTC Pink Sheets: ACTC) and its collaborators reported today that human oocytes (or 'eggs') have the capacity to extensively reprogram adult human cells. The research, which appears online ahead of print in the journal Cloning and Stem Cells (Editor-in-Chief: Sir Ian Wilmut; published by Mary Ann Liebert, Inc.) demonstrates that...

A South Korean biotech firm said on Thursday it has developed a new cloning technology that is expected to make cloning pet dogs easier and significantly cheaper. RNL Bio introduced the new method to clone dogs using stem cells derived from fat tissue that greatly increases the likelihood of a successful clone. Pet owners have been paying upwards of $100,000 to clone a pet dog, but RNL Bio says the newly efficient technique could drop costs as much as 50 percent. However, those interested in...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
