Stem cells for fat have circadian clock
New discoveries about the circadian-clock machinery in the precursors to fat cells may explain why shift workers are prone to metabolic diseases, such as diabetes, a Stanford study finds.
RNA labeling reveals stem cell secrets
The Stanford research suggests that any conclusions about stem cell function based on studies of stem cells in lab dishes may now need to be reconsidered in light of the fact that the cells’ biology changes during isolation.
Researchers discover lung stem cell in mice
Stanford scientists have found a cell that creates the two different compartments in the mouse lung. They hope their discovery could lead to better therapies for people with lung disease.
Animals don’t fully mimic human immune response
“Humanized” mice are used to study human immune responses, but they are inadequate for stem cell studies, say Stanford researchers. Optimized models are needed for clinical decision-making.
Molecule aids muscle regeneration in mice
Stanford researchers have found that a metabolite stimulates mouse muscle stem cells to proliferate after injury, and anti-inflammatory drugs, frequently taken after exercise, block its production and inhibit muscle repair.
Protein helps speed wound healing
Pretreatment with a stem-cell-activating protein significantly enhances healing in mice, Stanford researchers say. The approach could eventually help people going into surgery or combat heal better from injuries they sustain.
Patients blinded by treatment touted as ‘trial’
After three patients were blinded following a treatment marketed as a stem cell clinical trial, Stanford ophthalmologist Jeffrey Goldberg calls for increased patient education and regulation.
Scientists awarded stem cell grants
The grants to Stanford researchers target stem cell-based therapies for autoimmune disorders, liver disease and cystic fibrosis.
Rat-grown pancreases help save diabetic mice
Growing organs from one species in the body of another may one day relieve transplant shortages. Now researchers show that islets from rat-grown mouse pancreases can reverse disease when transplanted into diabetic mice.
Fewer bone stem cells in diabetes impedes healing
Stanford researchers found that activating bone stem cells helps repair fractures in diabetic mice. Applying a protein to the fracture site increased the expression of key signaling proteins and enhanced healing in the animals.
