Scientists and ethicists put the latest stem-cell ‘breakthrough’ under the microscope.
Backtracking On Stem Cell Advance
The California biotech company that grabbed headlines last week for sparing human embryos while creating stem cells in fact destroyed all 16 embryos used in the experiments.
Adult Stem Cells Are Touchy-Feely, Need Environmental Clues for Change
Researchers have discovered that mesenchymal stem cells, which regularly reside in the bone marrow as part of the bodys natural regenerative mechanism, depend on physical clues from their local environment in order to transform into different types of tissue.
Decision-Making Circuitry of Blood Stem Cells Mapped
Experimental work has led to the first mathematical model of a regulatory circuit that blood-forming stem cells use to decide what kind of white blood cell they will become. The model explains the puzzling behavior of differentiating stem cells, in which they simultaneously assume genetic signatures of different cell types before committing to one identity.
Rats Born to Mice in Bizarre Lab Work
Scientists have generated rats from mice that developed rat sperm.
A Switch Between Life and Death
Researchers have discovered how a signal tells cells whether to grow or die. This is important as growth needs to be controlled or the result may be defects in embryonic development or cancer in adults.
Northwest Biotherapeutics Updates Brain Cancer Clinical Data
63% of patients are still alive after more than two years, compared with 26% receiving standard treatments.
Players Storing Children’s Stem Cells as “Repair Kit”
Some leading English soccer players are storing stem cells from their newborn babies as a potential future treatment for their own career-threatening sports injuries.
Stem Cell Treatment Warning
A company operating out of South Africa is charging tens of thousands of pounds for stem cell treatments, using cells that should not be injected into people, putting the lives of their vulnerable and chronically ill patients at risk.
Study Finds How Organs Monitor Themselves During Early Development
A discovery involving a feedback loop governing ovarian development could lead to treatments of many disorders and could show how the power of stem cells could be harnessed for organ regeneration.
ABSTRACTS, REVIEWS & SPECIAL REPORTS
Cancer Regression in Patients After Transfer of Genetically Engineered Lymphocytes
Using a retrovirus encoding a T cell receptor, the researchers here report the ability to specifically confer tumor recognition by autologous lymphocytes from peripheral blood.
