What’s Good For The Mouse Is Good For The Monkey: Skin Cells Reprogrammed Into Stem Cells
December 4, 2008 — Scientists have successfully created the first induced pluripotent stem cell lines from adult monkey skin cells. The research, published in the journal Cell Stem Cell, demonstrates that the method of ... > full story -
Gene Mutation May Cause Immature Lungs In Newborns
December 3, 2008 — Scientists have identified a gene critical to lung maturation in newborns and the production of surfactant, which lines lung tissues and prevents the lungs from collapsing. Scientists deleted the ... > full story -
Vaccine Against Multiple Sclerosis? Mouse Experiment Yields Promising Results
December 3, 2008 — Researchers in Germany have succeeded in vaccinating mice with specially treated, autologous immune cells and preventing them from developing encephalitis, which is similar to multiple sclerosis in ... > full story -
Cells Reorganize Shape To Fit The Situation, Scientists Discover
December 1, 2008 — Flip open any biology textbook and you're bound to see a complicated diagram of the inner workings of a cell, with its internal scaffolding, the cytoskeleton, and how it maintains a cell's shape. Yet ... > full story -
Insights Into Adaptive Ability Of Cells May Help Explain How Cancer Eludes Body's Natural Defense
December 1, 2008 — Scientists have shed light on the ability of cells to adapt to disruptions to their basic division machineries -- a finding that may help explain how cancer cells elude the body's natural defense ... > full story -
New Way Epigenetic Information is Inherited: Small RNAs Inherited From Mother Determines Offspring’s Fertility Trait
December 1, 2008 — Scientists report that small RNA molecules called piRNAs can be passed directly from one generation to the next in fruit flies, thereby passing the trait of fertility from the mother to progeny. This ... > full story -
Genetic Patterning In Fruit Fly Development Identified
December 1, 2008 — No matter the species, from flies to humans, we all start the same: a single-cell fertilized egg that embarks on an incredible journey. The specifics of this journey are being uncovered by one ... > full story -
Reprogrammable Cell Type Depends On Single Gene To Keep Its Identity
December 1, 2008 — Scientists have discovered that a certain differentiated cell type is so ready to change its identity that it requires the constant expression of a gene called Prox1 to dissuade ... > full story -
Dictyostelium Cells Shown To Lay 'Breadcrumb Trail' As First Step In Multicellular Formation
December 1, 2008 — When starved of their food source and then presented with a chemoattractant signal like cAMP, individual Dictyostelium cells acquire a polarized morphology and aggregate to form a migrating stream. ... > full story -
Cell Movements Totally Modular, Study Shows
November 30, 2008 — A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics -- that the proteins driving cell behavior are doing so much multitasking ... > full story
