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 ...

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 ...

Cells are collective thinkers

Cells, like humans, cast votes to make decisions as a group. But how do they know what to vote for? Researchers at the Francis Crick Institute and King's College London have uncovered how cells actively seek information in ...

Metal-ion breakthrough leads to new biomaterials

Metals such as iron and calcium play a crucial role inside the human body, so it's no surprise that bioengineers would like to integrate them into the soft, stretchy materials used to repair skin, blood vessels, lungs and ...

Peptide hydrogels could help heal traumatic brain injuries

Traumatic brain injury (TBI)—defined as a bump, blow or jolt to the head that disrupts normal brain function—sent 2.5 million people in the U.S. to the emergency room in 2014, according to statistics from the U.S. Centers ...

A chip with blood vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Skin gel allows wounds to heal without leaving a scar

A team of researchers at Huazhong University of Science and Technology has developed a silk protein-based gel that they claim allows for skin healing without scarring. In their paper published in the journal Biomaterials ...

Biomaterial could keep tooth alive after root canal

A root canal ranks high on most people's list of dreaded dental procedures. Although the lengthy and sometimes painful surgery relieves the agony of an infection, a root canal results in a dead tooth with no living soft tissue, ...
