Technique may help stem cells generate solid organs

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,

Artificial skin created using stem cells

In a first, scientists have grown artificial skin using stem cells derived from the umbilical cord.

Scientists from the Tissue Engineering Research Group at the Department of Histology at the University of Granada demonstrated the ability of Wharton jelly mesenschymal stem cells to turn to oral-mucosa or skin-regeneration epithelia.

Journal STEM CELLS Awards Pioneering Research into Limbal Stem Cell Deficiency

A young scientist who led research into the use of stem cells from hair follicles to treat the ocular surface disease has been named the winner of the Young Investigator Award by the journal STEM CELLS.

Dr. Ewa Meyer-Blazejewska will be presented with her award at The Stem Cell Symposium, hosted by the University of Kragujevac in Serbia on October 15, 2011. The $10,000 prize is awarded annually to a young scientist whose paper has been judged to be of worldwide significance by a global

Stem cells show promise in cartilage repair

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

SPAIN – Stem Cells, First ‘Engineered’ Trachea Transplant

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
