A team of John Hopkins University undergraduates say they have found a way to quickly and easily embed a person’s stem cells into surgical thread, a procedure they believe may help improve healing and prevent re-injury.
The 10 biomedical engineering students developed the procedure as part of a contest sponsored by a medical technology company trying to patent the concept as a way to help patients recover from major orthopedic injuries, such as ruptured ligaments and tendons.
“Using sutures that carry stems cells to the injury site would not change the way surgeons repair the injury,” student team leader Matt Rubashkin,

British team pioneers reconstruction technique using enriched tissue
A remarkable reconstruction technique is being trialled by British surgeons, who are harvesting stem-cell-enriched fat from women’s bodies to plug the dip often left by breast cancer operations.
The procedure appears to restore the softness and suppleness of breast tissues, undoing the damage frequently caused by lumpectomy and radiotherapy. Early signs indicate that it also eases the considerable pain with which patients are often left after treatment.
More than 31,000 women a year in Britain with early-stage breast cancer undergo operations in which just the lump and a healthy margin of tissue
Ciaran Finn-Lynch, who became the first child in the world to undergo a groundbreaking trachea transplant in March this year, is set to return home to Northern Ireland.
Ciaran underwent the transplant, which involved the removal of his own trachea replaced by a donor windpipe, at Great Ormond Street Hospital. Doctors then used Ciaran’s own stem cells from inside his body to build up the donor windpipe and ensure the organ was not rejected.
Four weeks ago, doctors were able to describe the transplant as a success for the first time after proving vascular supply had returned to

According to a recent article in Lancet magazine, the first “engineered” transplant in the world was a success. For the first time, a trachea was “tailored” to the patient before being implanted. 30 year old Colombian Claudia Castillo who suffered damage to her trachea due to tuberculosis was the patient in an operation that was particularly interesting for Italy, since the operation was performed in June by an international medical team led by Paolo Macchiarini, the head of Thoracic Surgery at the Clinic de Barcelona, in collaboration with specialists from the Milan General Hospital, and the
In a world first in children, British and Italian doctors have transplanted a new airway (trachea) into a child and used the child’s own stem cells, in the body, to rebuild it.
The donated trachea was stripped of the donor’s old cells, down to the inert collagen. The child recipient’s bone marrow stem cells were collected, and applied to the graft in situ in the body, to rebuild the cellular component of the trachea. Thus the child’s own cells will be used to make the new airway sealed and effective.
This is the first time that this has been performed
