Researchers find stem cells from monkey teeth can stimulate growth and genera...

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 regenerative medicine, particularly therapies associated with the central nervous system.

What makes an axon an axon?

Inside every axon is a dendrite waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development. The results suggest that this transformation could occur after nerve cell damage.

New properties of skin stem cells

Recent research from the Swedish medical university Karolinska Institutet reveals completely new properties of the skin's stem cells ? discoveries that contradict previous findings. The studies, which are published in Nature Genetics, show amongst other things, that hair follicle stem cells can divide actively and transport themselves through the skin tissue.

Forsyth scientists trigger cancer-like response from embryonic stem cells

Scientists from The Forsyth Institute, working with collaborators at Tufts and Tuebingen Universities, have discovered a new control over embryonic stem cells' behavior. The researchers disrupted a natural bioelectrical mechanism within frog embryonic stem cells and trigged a cancer-like response, including increased cell growth, change in cell shape, and invasion of the major body organs. This research shows that electrical signals are a powerful control mechanism that can be used to modulate cell behavior.

Yamanaka eliminates viral vector in stem cell reprogramming

Shinya Yamanaka MD, PhD, of Kyoto University and the Gladstone Institute of Cardiovascular Disease (GICD) has taken another step forward in improving the possibilities for the practical application of induced pluripotent stem (iPS) cell technology.

Fat-regenerating 'stem cells' found in mice

Researchers have identified stem cells with the capacity to build fat, according to a report in the October 17th issue of the journal Cell, a Cell Press publication. Although they have yet to show that the cells can renew themselves, transplants of the progenitor cells isolated from the fat tissue of normal mice can restore normal fat tissue in animals that are otherwise lacking it.

Scientists identify genes capable of regulating stem cell function

Scientists from The Forsyth Institute, Boston, MA, and the Howard Hughes Medical Institute at the University of Utah School of Medicine have developed a new system in which to study known mammalian adult stem cell disorders. This research, conducted with the flatworm planaria, highlights the genetic similarity between these invertebrates and mammals in the mechanisms by which stem cell regulatory pathways are used during adult tissue maintenance and regeneration. It is expected that this work may help scientists pursue pharmacological, genetic, and physiological approaches to develop potential therapeutic targets that could repair or prevent abnormal stem cell growth which can lead to cancer.

Embryonic stem cells might help reduce transplantation rejection

Researchers have shown that immune-defense cells influenced by embryonic stem cell-derived cells can help prevent the rejection of hearts transplanted into mice, all without the use of immunosuppressive drugs.

Scientists isolate cancer stem cells

After years of working toward this goal, scientists at the OU Cancer Institute have found a way to isolate cancer stem cells in tumors so they can target the cells and kill them, keeping cancer from returning.
