Cells in such tissues are said to be metabolically coupled.
Such tissues are widely used in orthopedic surgery to repair bad knees and other muscular or skeletal injuries.
Then researchers realized such tissues might help their search for cures and started to save them -- but less than comprehensively.
The unique benefits and risks of sharing data obtained from such tissues will need to be considered.
Third, if such tissues prove too provocative to patients' immune systems, Geron is working on ways to generate embryonic cells from patients' own mature cells.
The defining feature of such tissues is the presence of a central, interconnected luminal network.
Such tissues could also enable the further study of Wnt signaling.
In such tissues there is probably no special stem-cell population, and any cell can participate in tissue regeneration when required.
Felicia Nestor, the food safety director at the Government Accountability Project, another advocacy group, added that given the possible dangers of eating such tissues, "it's just unacceptable that the American public should be put in this position".
The fear that such tissues would have short telomeres and abbreviated lifetimes now seems dispelled by the news from the cloned cows, and that makes the shortness of Dolly's telomeres appear to be an unexplained anomaly.
The 3D arrangement of the collagen fibers is crucial to understand the mechanical behavior of such tissues.
