The awards are the third in the agency’s “tools and technology” grants, which encourage researchers to develop new methods and techniques to overcome stumbling blocks in the field.

Thought leaders from several disciplines will gather at the Stanford campus April 2-3 to discuss how to harness many branches of medicine to solve health problems in pregnancy, infancy and childhood.

The epigenome controls gene expression across diverse cell types, and integrates genetic and environmental signals. A new reference map will help interpret the genetic basis for disease.

Researchers disabled aging-associated genes in the short-lived African killifish, including one for an enzyme called telomerase, whose absence caused humanlike disease in the animal.

Stem cell pioneer Irving Weissman was recognized with the Brupbacher Prize for isolating cancer stem cells, as well as with the McEwen Award for his research on adult stem cells from a variety of human tissues and cancers.

Researchers delivered a modified RNA that encodes a telomere-extending protein to cultured human cells. Cell proliferation capacity was dramatically increased, yielding large numbers of cells for study.

The discovery of a skeletal stem cell in mice sets the stage for new methods to grow cartilage and bone for use in medical therapies.

Researchers knew that a drug administered to remove iron from the blood could also overcome diabetic interference with blood vessel formation, but finding the right way to deliver it for this use was the challenge.

In a mouse model of Duchenne muscular dystrophy, muscle stem cells express connective-tissue genes associated with fibrosis and muscle weakness, according to a new study.

In laboratory experiments, researchers were able to correct a collagen defect — the source of a blistering skin disease — in stem cells made from patients.
