Biocompatible Bandage accelerating natural bone healing for Severely Broken Bones

Researchers at King’s have developed a material that allows transplantation of bone-forming stem cells into severe bone fractures and speeds up the healing process.

Biocompatible Bandage

Researchers in the UK have devised a bandage like biomaterial that transplants stem cells into severe bone fractures. The easily applied bandage significantly speeds up the healing process, improves recovery, and reduces the risk of infections and poor outcomes for very serious injuries.

The biomaterial developed at King’s College London simulates structures that are part of healthy human bones. The bandage can then be stuck to a fracture like a plaster, amplifying the natural healing process.

In order to speed up bone healing, the bandage is coated in a protein involved throughout the body in the growth and repair of tissue. Additionally, the material grows bone cells from stem cells in a 3D gel embedded in the bandage. When the bandage is patched to a fracture, these bone cells are transplanted to the site of injury.

Most broken bones do not require intensive medical care. Typically, doctors will put a broken arm or leg into a cast. The cast doesn’t heal broken bones on their own, but rather hold the affected area in place so the bone heals naturally and straight.

In particularly severe fractures, surgery is often necessary. Sometimes, doctors will insert metal pins and other implants to hold everything in place while the bone heals.

Other times, instead of synthetic implants, bone is taken from elsewhere in the body for transplant at the site of injury.However, following a serious injury, the body’s ability to heal is weakened. This is particularly true for the elderly.

This is why a ‘bone like bandage’ is appealing: it supports and accelerates the healing of bone fractures without the need for synthetic implants. It is also biocompatible and safe as the researchers designed it to specifically target fracture sites, so it does not leak to healthy tissue.

The bandages can even be made biodegradable to simply be absorbed by the body when healing has finished. These safety features, and the powerful effect of the bandages, means that they could have the potential to be used in hospitals.

“Our technology is the first to engineer a bone-like tissue from human bone stem cells in the lab within one week, and successfully transplant it in the bone defect to initiate and accelerate bone repair.

The concept of the 3D-engineered tissue and the bandage has the potential to be developed to different injured tissues and organs,” first author Dr. Shukry Habib, from King’s College Centre for Stem Cells & Regenerative Medicine London, said in a statement.
