Healing

Scar tissue is an effective short-term solution to quickly patch up wounded skin, but it’s not so great long-term. A new hydrogel helps by triggering a regenerative immune response, so skin heals healthier and stronger without scarring.

When surgery is performed on infants in utero, they're often born without any scars. This comes thanks to a special quality of their skin which scientists now believe could be replicated in adults, potentially leading to scar-free wound treatments.

When suturing wounds within the body, there's a risk of damaging the tissue, and of the development of infections. A new surgical glue could reduce the need for sutures, though, plus it could close wounds faster while also delivering medication.

More and more, we're hearing about scaffolding-like materials that are used to help heal bone injuries. A new one is claimed to be particularly versatile, as it's inspired by Lego building blocks.

We've already heard about implantable materials with a scaffolding-like microstructure, that help heal broken bones by giving bone cells a place to migrate into. A new one could work even better, though, by also providing electrical stimulation.

Ripping Band-Aids off your skin is never fun – but imagine having one on your heart or lung. Researchers have now created surgical tape that can stick to wet surfaces like organs, and more importantly, be removed safely when it’s no longer needed.

Stem cells are powerful tools that could one day unlock new frontiers in regenerative medicine. Now, a new study has shown that a certain type of stem cell can be delivered into injured tissues with dissolvable microneedles, to heal wounds.

A combination of two commonly used drugs may boost the release of stem cells from bone marrow and accelerate the healing of broken bones. The researchers suggest clinical trials could progress rapidly as the drugs have already been shown to be safe.

The treatment of chronic wounds often involves the application of different medications, at different stages in the healing process. A new electronic bandage could allow this to happen, but without having to be removed for each application.

Scientists at the University of Toronto have spent years developing a portable device that can print out large sheets of "bio ink" to boost the healing process from severe burns, and have just proved its abilities in pigs for the first time.

Some studies suggest anti-inflammatory drugs can slow wound healing and bone repair. New research reveals our natural circadian clocks play a major role in healing, and anti-inflammatory drugs may be more effective if taken in the morning.

Polysporin may be in for some serious competition, as Swedish scientists have created a healing gel that not only kills antibiotic-resistant bacteria, but also reduces inflammation within wounds. It could someday replace antibiotic-based medications.
