A 21-year-old leukemia patient underwent pioneering surgery in a Shanghai hospital Wednesday, when doctors transfused 30 milliliters of umbilical-cord blood donated by a Shanghai cord bank. Today they will transplant a batch of his father’s stem cells, which are an imperfect match.
This combination of umbilical-cord blood and half-matched stem cells can offer lifesaving transplant opportunities to many more patients than traditional methods, which require a perfect match between patient and donor, said doctors from Shanghai No. 1 People’s Hospital.
It will be a month before results of the transplant are determined.
About 40,000 to 50,000

“Stem cells are no longer only the future of aesthetic surgery, they are the present,” said Alessandro Gennai, an associate plastic surgeon at the European Academy of Facial Plastic Surgery (EAFPS). For the past year, Gennai has been using a modified technique used to preserve stem cells in lipofilling procedures. “I have already performed numerous operations, with excellent results and without side-effects,” said the surgeon from Bologna, “therefore I can say that lipofilling is the best solution for someone who wants to eliminate wrinkles before the summer. The procedure lasts 30
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
