Dr Shai Meretzki, chief executive of Bonus BioGroup, with the human bones grown from stem cellsThe development opens the way for patients to have broken bones repaired or even replaced with entire new ones grown outside the body from a patient's own cells.
The researchers started with stem cells taken from fat tissue. It took around a month to grow them into sections of fully-formed living human bone up to a couple of inches long.
The first trial in patients is on course to be conducted later this year, by an Israeli biotechnology company that has been working with academics on the technology.
Professor Avinoam Kadouri, head of the scientific advisory board for Bonus BioGroup, said: "There is a need for artificial bones for injuries and in operations.
"We use three dimensional structures to fabricate the bone in the right shape and geometry. We can grow these bones outside the body and then transplant it to the patient at the right time.
"By scanning the damaged bone area, the implant should fit perfectly and merge with the surrounding tissue. There are no problems with rejection as the cells come from the patient's own body."
The technology, which has been developed along with researchers at the Technion Institute of Research in Israel, uses three dimensional scans of the damaged bone to build a gel-like scaffold that matches the shape.
Stem cells, known as mesenchymal stem cells, which have the capacity to develop into many other types of cell in the body, are obtained from the patient's fat using liposuction.
