- Simple recipe turns human skin cells into embryonic stem cell-like cells
11-20-2007 · EurekAlert!
A simple recipe -- including just four ingredients -- can transform adult human skin cells into cells that resemble embryonic stem cells, researchers report in an immediate early publication of the journal Cell, a publication of Cell Press. The converted cells have many of the physical, growth and genetic features typically found in embryonic stem cells and can differentiate to produce other tissue types, including neurons and heart tissue, according to the researchers.

- Cell growth technology promises more successful drug development
09-18-2007 · EurekAlert!
Scientists have developed unique technology to grow stem cells and other tissue in the laboratory in conditions similar to the way they grow in the human body. The technology, developed and patented by scientists at Durham University, UK, and its spin-out company ReInnervate Limited, is a plastic scaffold which allows cells to be grown in a more realistic three-dimensional form compared to the traditional flat surface of a Petri dish.

- Scientists find stem cell switch
07-26-2007 · EurekAlert!
Scientists have discovered how plant stem cells in roots detect soil structure and whether it is favourable for growth. Poor soil structure is a problem in tropical agriculture, where soil becomes compact as it dries out. Professor Liam Dolan, of the John Innes Centre in Norwich, UK and his team determined that the plant hormone ethylene regulates cell division in root stem cells.

- Forsyth scientists gain new understanding of adult stem cell regulation
08-01-2007 · EurekAlert!
Forsyth Institute scientists have discovered an important mechanism for controlling the behavior of adult stem cells. Research with the flatworm, planaria, found a novel role for the proteins involved in cell-to-cell communication. This work has the potential to help scientists understand the nature of the messages that control stem cell regulation -- such as the message that maintain and tells a stem cell to specialize and to become part of an organ (e.g., liver or skin).

- 'Mini transplant' patients' outcomes similar using related and unrelated donor cells
12-03-2007 · EurekAlert!
People who undergo nonmyeloablative stem-cell transplants, or 'mini transplants,' for leukemia, lymphoma and other blood cancers have comparable outcomes regardless of whether they receive tissue-matched stem cells from a related or unrelated donor, according to new findings by researchers at Fred Hutchinson Cancer Research Center.

- First human trial tests stem-cell-based treatment for heart attacks
03-25-2007 · EurekAlert!
Previous research on the efficacy of stem cell therapy for heart repair has shown possible benefit from mesenchymal stem cells (MSCs) -- cells found in bone marrow that create connective tissue, bone and cartilage. A study presented today at the American College of Cardiology's Innovation in Intervention: i2 Summit reveals the results of the first human trial using MSCs for the treatment of myocardial infarction (MI, or heart attack).

- Can you hear me now? Stem cells enhance hearing recovery
06-25-2007 · EurekAlert!
Researchers have shown that bone marrow stem cells injected into a damaged inner ear can speed hearing recovery after partial hearing loss. The related report by Kamiya et al, "Mesenchymal stem cell transplantation accelerates hearing recovery through the repair of injured cochlear fibrocytes," appears in the July issue of The American Journal of Pathology.
