Adult stem cells could be used in an innovative technique to reproduce bone in patients lacking bone in the jaw. The new method was developed to rebuild the dental arch with an outpatient procedure under local anesthesia for people who are not able to undergo certain types of dental procedures. The procedure, developed by the University of Freiburg (Germany) has been performed in Italy by Luigi Montesani, a surgeon at Tufts University in Boston. “The insertion of implants and procedures for bone augmentation,” explained Montesani, “are a priority when rehabilitating patients who have lost

Artificial intestines could be created thanks to stem cells. Intestinal stem cells grown in the laboratory have been manipulated to differentiate in order to produce all of the different types of cells that form intestinal epithelium, said a Dutch study, published in ‘Nature’ magazine by Hans Clevers of the Hubrecht Institute in Utrecht.
The study also outlines a more precise link between stem cells and their microenvironment.
It also offers a practical technique to generate new intestinal epithelium in the laboratory. Stem cells, which express the Lgr5 protein, were discovered on several specific regions of
