Nanoparticle 'backpacks' restore damaged stem cells

Within a newborn's umbilical cord lie potentially life-saving stem cells that can be used to fight diseases like lymphoma and leukemia. That is why many new parents elect to store ("bank") their infant's stem cell-rich umbilical ...

Shape-morphing microrobots deliver drugs to cancer cells

Chemotherapy successfully treats many forms of cancer, but the side effects can wreak havoc on the rest of the body. Delivering drugs directly to cancer cells could help reduce these unpleasant symptoms. Now, in a proof-of-concept ...

The complex dynamics of stem cell tethers and slings

An innovative experiment design shows, in real time and at the scale of a single molecule, how stem cells slow their rolling inside the circulatory system by growing long tethers that attach to the inner surfaces of blood ...

First 3D-bioprinted structured Wagyu beef-like meat

Scientists from Osaka University used stem cells isolated from Wagyu cows to 3D-print a meat alternative containing muscle, fat, and blood vessels arranged to closely resemble conventional steaks. This work may help usher ...

Gel drops for regenerative medicine

Micrometer-sized gel drops can provide the extracellular architecture needed for cells to grow and proliferate. The cell-carrying gels, made of self-assembling ultrashort peptides that form supportive nanofiber networks, ...

Getting oxygenated blood to exercising muscles

ETH Zurich Professor Katrien De Bock and her team have discovered a certain type of blood vessel cell in muscles that multiplies rapidly upon exercise, thereby forming new blood vessels. Researchers can use this to find novel ...
