Doctors issue caution over missed cancer diagnoses tied to immune disorder

Physicians who specialize in a devastating and aggressive immune disorder called hemophagocytic lymphohistiocytosis (HLH) report in a new study that extra care should be taken to ensure an HLH diagnosis doesn’t obscure possible underlying cancers.

Can we teach heart cells to grow up?

Scientists around the world have been trying to replace damaged heart tissue using lab-made heart-muscle cells (cardiomyocytes), either injecting them into the heart or applying patches laced with the cells. But results to date have been underwhelming. “If you make cardiomyocytes in a dish from pluripotent stem cells, they will engraft in the heart and form muscle,” says William Pu, MD, […]
