Carnegie Mellon researchers to develop new drug delivery system
Carnegie Mellon University's Stefan F. Zappe is using adult neural stem cells to develop a new stem cell-based drug delivery therapy that may ultimately help treat a variety of inherited genetic disorders like Hunter syndrome. view more (2007-11-05)
Stem-cell therapy could have benefits and risks for heart-attack patients (pp 746, 751, 783)
Two studies in this week's issue of THE LANCET raise questions about the feasibility and safety of stem-cell therapy for heart disease, suggesting that such treatments could have both benefits and drawbacks. Adult haemopoietic stem cells give rise to blood cells, and are thought to be able to generate other types of cell. Recent studies have... view more... (2004-03-03)
New hope for regenerative medicine
In the February 15th issue of G&D, Dr. K. John McLaughlin and colleagues report on their success in using uniparental embryonic stem cells to replace blood stem cells in mice. view more (2007-02-15)
With few factors, adult cells take on character of embryonic stem cells
With the introduction of just four factors, researchers have successfully induced differentiated cells taken from mouse embryos or adult mice to behave like embryonic stem cells. view more (2006-08-25)
Powerful technique for multiplying adult stem cells may aid therapies
Adult stem cells may be free of the ethical concerns that hamper embryonic stem cell research, but they still pose formidable scientific challenges. Chief among these is the doggedness with which adult stem cells differentiate into mature tissue the moment they're isolated from the body. view more (2006-01-23)
New 'control knobs' for stem cells identified
Natural changes in voltage that occur across the membrane of adult human stem cells are a powerful controlling factor in the process by which these stem cells differentiate, according to research published by Tufts University scientists. view more (2008-12-04)
Stem Cells from Monkey Teeth Can Stimulate Growth and Generation of Brain Cells
Researchers at the Yerkes National Primate Research Center, Emory University, have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells. Findings from this study, available in the October issue of the journal Stem Cells, suggest dental pulp stem cells show promise for use in cell therapy and... view more... (2008-11-12)
DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory. view more (2008-01-23)
Stem cell identity in culture may strongly depend on the cellular microenvironment
Identification, isolation and large scale culture of stem cells for potential medical applications is a major challenge in cell biology. view more (2007-04-25)
Penn researchers find key developmental pathway activates lung stem cells
Researchers from the University of Pennsylvania School of Medicine found that the activation of a molecular pathway important in stem cell and developmental biology leads to an increase in lung stem cells. Harnessing this knowledge could help develop therapies for lung-tissue repair after injury or disease. view more (2008-06-18)
Scientists uncover the potential to control adult stem cells
Research being presented today (10 April) at the UK National Stem Cell Network Annual Science Meeting in Edinburgh represents a step towards the use of Adult Stem Cells (ASCs) to repair damaged tissue. view more (2008-04-10)
Xie Lab demonstrates the role of microRNA pathway
Ting Xie, Ph.D., Associate Investigator, and Zhigang Jin, Ph.D., Postdoctoral Research Associate in the Xie Lab, have published results showing that the microRNA pathway is essential for controlling self-renewal of germline stem cells and somatic stem cells in the Drosophila ovary. view more (2007-02-16)
Master regulatory gene of epithelial stem cells identified
The skin's ability to replace the tissue it sloughs off is controlled by a variety of genes. A new study from Harvard Medical School published in the May 4 issue of Cell, however, identifies a "master regulator" of this regeneration process not only for skin, but for many epithelial tissues including breast, prostate, and urogenital... view more...

Stem cell chicken and egg debate moves to unlikely arena: the testes
Logic says it has to be the niche. As air and water preceded life, so the niche, that hospitable environment that shelters adult stem cells in many tissues and provides factors necessary to keep them young and vital, must have emerged before its stem cell dependents. view more (2008-07-21)
Neural stem cell differentiation factor discovered
Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. view more (2009-06-30)
Mechanism in cells that generate malignant brain tumors may offer target for gene therapy
Researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate. view more (2008-10-27)
Embryonic stem cells used to grow cartilage
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. view more (2007-09-07)
Adult stem cells from human cord umbilical cord blood successfully engineered to make insulin
In a fundamental discovery that someday may help cure type 1 diabetes by allowing people to grow their own insulin-producing cells for a damaged or defective pancreas, medical researchers here have reported that they have engineered adult stem cells derived from human umbilical cord blood to produce insulin. view more (2007-05-29)
Pittsburgh researchers identify source of multipotent stem cells with broad regenerative potential
In a promising finding for the field of regenerative medicine, stem cell researchers at Children's Hospital of Pittsburgh of UPMC have identified a source of adult stem cells found on the walls of blood vessels with the unlimited potential to differentiate into human tissues such as bone, cartilage and muscle. view more (2008-09-22)
A new method of adult stem cell growth efficacious in treatment of disorders of the cornea
A new method of adult stem cell growth, designed in the Area of Cellular Therapy of the University Clinic (University of Navarra), has demonstrated its efficacy for its capacity to grow cornea stem cells. view more (2007-07-20)
