Healing

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.

Although essential oils are typically associated with aromatherapy, new research indicates that medicines based on them could also help to heal skin wounds. It all comes down to a certain substance in some of the oils, that reduces inflammation.

When a bone-break occurs, the body floods the injury site with a healing biochemical known as adenosine. A new bandage is designed to absorb that substance, keeping it around so it can do more work.

Although sutures are routinely used to close wounds within the body, they can actually damage fragile biological tissue, causing infections or other complications. Scientists at MIT have developed what could be a better way to go, in the form of a double-sided tape.

When someone has a severe burn, a protective covering needs to be temporarily grafted onto the wound site. Although that covering typically consists of skin from a human cadaver, live-cell pig skin has now been used on a patient for the first time.
