Gene therapy promising for growing tooth-supporting bone

...P-7 is part of a family of proteins that regulates cartilage and bone formation. Recent studies have shown that BMPs are present in tooth development and periodontal repair. This study mixed BMP-7 genes with an inactivated virus in a gel-like carrier and injected it into wounds. Giannobile said using a virus,...

Nano-bumps could help repair clogged blood vessels

...ave shown in a series of experiments that bone and cartilage cells in petri dishes attach better to materials that possess smaller surface bumps than are found on conventional materials used to make artificial joints. The smaller features also stimulate the growth of more new bone tissue, which is critical for...

Scientists discover that three overlapping signals in embryo help get the backbone right

...nt, this protein factor is critical in laying down cartilage to make joints, and even plays an important role after birth. Recently, he and Stanford University colleagues showed that noggin may be important in preventing the premature fusion of the bones in the skull, and thus may be critical to allowing the b...

Researchers Closer To Helping Hearing-Impaired Using Stem Cells

...ls -- a type of stem cell from which fat, bone and cartilage normally develop. “We were interested in marrow stromal cells because of their potential for use in autologous cell-based therapy,?said Dr. Hashino, referring to cell transplantation in which a patient’s own cells are used in treatment. The cells ca...

New research could help us deliver genes for new bone formation

...cientists are working on new methods to regenerate cartilage and bone by delivering genes to stem cells within the body to instruct them to turn into bone cells. The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), could lead to a new approach to tissue engineering. With ...

Clinical trial to test stem cell approach for children with brain injury

...nchymal stem cells, which differentiate into bone, cartilage and fat cells, and research indicates can also differentiate into neurons; and hematopoietic stem cells, which form all the cells needed for blood. Preclinical research indicates that the mesenchymal stem cells play the major role in producing new...

Scientists use stem cells to grow cartilage

...essfully converted human embryonic stem cells into cartilage cells, offering encouragement that replacement cartilage could one day be grown for transplantation. Cartilage is the dense connective tissue usually found ...

From one cell, many possible cures

...sue . . . regenerate injured bone . . . create new cartilage or skin . . . even reverse nerve damage. Human stem cells offer tremendous hope for the development of revolutionary medical treatments for these and a variety of other human health problems. Up until now, however, stem cell research has been slowed...
