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.
Samuel Strober awarded $6.6 million
The California Institute for Regenerative Medicine awarded Samuel Strober, MD, $6.6 million to study a “deceptively simple” way to help kidney transplant recipients tolerate their new organ.
Stem cells police themselves to reduce scarring
Stem cells produce a decoy protein to attenuate growth signals. Artificially regulating this pathway might help keep muscles supple in muscular dystrophy or during normal aging, researchers hope.
Canine cancer immunotherapy
The work extends research by Stanford scientists who found that blocking CD47 might be useful in treating human cancer.
Paving the way for gene therapy
Using the CRISPR gene-editing technique in stem cells, Stanford researchers repaired the gene that causes sickle cell disease, and the mended stem cells were successfully transplanted into mice.
Fat cell-maturation hormone found
Mature fat cells produce a hormone that regulates the differentiation of nearby stem cells in response to glucocorticoid hormones and high-fat diets, Stanford researchers have found.
Dietary approach to depleting stem cells
A new study shows that a diet deficient in valine effectively depleted the blood stem cells in mice and made it possible to perform a blood stem cell transplantation on them.
