Johns Hopkins tissue engineers have used tiny artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age.
Reporting online June 4 in the Proceedings of the National Academy of Sciences, investigators say they have produced an important component of cartilage in both laboratory and animal models. While the findings are still years away from use in people, the researchers say the results hold promise for devising new techniques to help the millions who

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
Life Stem Genetics announced today a strategic collaborative agreement with American CryoStem Corporation.
CRYO is a leading developer, marketer and global licensor of patented adipose tissue-based cellular technologies for the Regenerative and Personalized Medicine industries.
Adipose tissue is an anatomical term for loose connective tissue (fat) composed of adipocytes (cells). It is used in LIFS stem cell procedures and currently is extracted via liposuction each time a patient has a treatment.
SANUWAVE Inc., an emerging medical technology company focused on the development and commercialization of non-invasive, biological response activating devices in the regenerative medicine area, reported that scientific findings titled “Extracorporeal Shock Wave Stimulation of Osteoprogenitor Cells” were presented at the 2009 International Bone-Tissue-Engineering Congress (“Bone-Tec”) in Hannover, Germany, which was held October 9-11, 2009.
Dr. Myron Spector, PhD, Professor of Orthopaedic Surgery (Biomaterials) at Harvard Medical School, Director of Orthopaedic Research at Brigham and Women’s Hospital and Director of Tissue Engineering at VA Boston Healthcare System, was an invited guest speaker at the Conference. The

Stem cells can thrive in segments of well-vascularized tissue temporarily removed from laboratory animals, say researchers at the Stanford University School of Medicine. Once the cells have nestled into the tissue’s nooks and crannies, the so-called “bioscaffold” can then be seamlessly reconnected to the animal’s circulatory system.
The new technique neatly sidesteps a fundamental stumbling block in tissue engineering: the inability to generate solid organs from stem cells in the absence of a reliable supply of blood to the interior of the developing structure.
“Efforts to use tissue engineering to generate whole organs have largely failed,” said Geoffrey Gurtner,
