A normal strong bone may be created when the tissue structure is restored by stem cells.
New means developed at the Southhampton hospital (Great Britain) allows the patients with femoral neck and head traumas to avoid traditional prosthesis implantation. The doctors offered to use bones fragments with suspension taken from the patient and the donor's stem cells. Five patients out of six underwent successful replacement of the broken
bone tissue by healthy one.
The effect of stem cells allowing an ordinary bone fragment to be grafted successfully at new place can be explained by two reasons. First of all stem cells were not converted to osteocytes (bone tissue cells), periosteum cells or any other type of cells. Stem cells may undergo multiple cell division instead of their special function performance. This is the second valuable property of stem cells. And only then they are converted to some type of mature cells.
Recently the scientists have managed to grow a new tooth for the mouse using the mixture of two stem cells types. Now the medics have restored the bone tissue structure with the help of stem cells. During the interview for Sky News Richard Oreffo, the professor of the Southhampton university stated that stem cells also contain the substances which help blood vessels to grow.
