Sir Martin Evans wins Nobel prize for stem cell research

Medical Research Council funded scientist Sir Martin Evans, has been awarded the Nobel Prize in Physiology or Medicine for 2007 alongside Mario R. Capecchi and Oliver Smithies for their discoveries of "principles for introducing specific gene modifications in mice by the use of embryonic stem cells".

Human embryonic stem cells remain embryonic because of epigenetic factors

A human embryonic stem cell is reined in - prevented from giving up its unique characteristics of self-renewal and pluripotency - by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.

Stem cells may aid national security

For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries.

Some cancer cells mimic stem cells to evade chemotherapy

Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented Sept. 19 by Vasyl Vasko, M.D. Ph.D., a pathologist at the Uniformed Services University of the Health Sciences (USU) at the American Association for Cancer Research's second International Conference on Molecular Diagnostics in Cancer Therapeutic Development.

Some cancer cells mimic stem cells to evade chemotherapy

Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to findings presented in Atlanta, Georgia at the American Association for Cancer Research's second International Conference on Molecular Diagnostics in Cancer Therapeutic Development.

Testes offer a promising new source of stem cells

After a decade of research, Howard Hughes Medical Institute scientists have succeeded in reprogramming adult stem cells from the testes of male mice into functional blood vessels and contractile cardiac tissue.

Women undergoing IVF to donate eggs for stem cell research in return for reduced treatment costs

The Medical Research Council (MRC) is to fund a research proposal from a team at the North East England Stem Cell Institute (NESCI) for a project to find ways of improving the efficiency of therapeutic cloning - a technique which would allow scientists to create patient-specific stem cells and develop regenerative therapies for many debilitating conditions such as diabetes, heart disease and Parkinson’s disease.

New Rensselaer tools speed stem cell research

Engineers at Rensselaer Polytechnic Institute have developed tools to help solve two of the main problems slowing the progress of stem cell research - how to quickly test stem cell response to different drugs or genes, and how to create a large supply of healthy, viable stem cells to study from only a few available cells.

Embryonic stem cell strategy advanced with UCSF finding

UCSF scientists are reporting what they say is a significant improvement in the technique for genetically reprogramming mouse cells to their embryonic state, a process that transforms the cells, in essence, into embryonic stem cells.

Shaken not stirred for embryonic stem cells

Embryos spend much of their time in the womb bobbing along with a mother's movement, and, surprisingly enough, new research from the Georgia Institute of Technology and Emory University suggests that embryonic stem cells may develop much better under similarly shaky conditions.

New technique for growing cartilage from human embryonic stem cells

Rice University biomedical engineers have developed a new technique for growing cartilage from human embryonic stem cells, a method that could be used to grow replacement cartilage for the surgical repair of knee, jaw, hip, and other joints.

Autophagy-induced signals are essential for normal development

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found.

Scientists identifiy successfully reprogrammed cells by looks alone

Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait.

Geron demonstrates hESC-derived cardiomyocytes improve heart function after myocardial infarction

Geron Corporation has reported its scientists and collaborators have demonstrated that human embryonic stem cell (hESC)-derived cardiomyocytes improve heart function when transplanted after myocardial infarction.

Novel heart repair therapy could be in the pipeline

The success of a new and experimental stem cell treatment used in animals could lead to a novel heart repair therapy for heart attack patients.

27 Aug 2007

Discovery of new gene family essential for embryonic development

The family controls the expression of genes crucial for stem cell maintenance and differentiation, and the results may contribute sig-nificantly to the understanding of the development of cancer.

Cancer stem cell scientists get $1.7 million to develop new leukemia drugs

"Modern cancer treatments fail to get to the root of the cancer - the stem cells - which is why many cancers recur despite aggressive treatment."

Scientists produce functioning neurons from human embryonic stem cells

Scientists with the Institute of Stem Cell Biology and Medicine at UCLA were able to produce from human embryonic stem cells a highly pure, large quantity of functioning neurons that will allow them to create models of and study diseases such as Alzheimer's, Parkinson's, prefrontal dementia and schizophrenia.

New treatment for glaucoma shows promise

Iowa State University researchers have developed a new technique that successfully treated rats for blindness caused by glaucoma.

Discredited Korean embryonic stem cells' true origins revealed

A report from researchers at Children's Hospital Boston and the Harvard Stem Cell Institute sheds new light on a now-discredited Korean embryonic stem cell line, setting the historical record straight and also establishing a much-needed set of standards for characterizing human embryonic stem cells.
