Faster method for growing adult stem cells for bone regeneration

A new method for utilizing adult stem cells for bone or other tissue regeneration without having to go through the intermediate step of expanding the number of cells in tissue culture has won a Kaye Innovation Award for a young doctoral student at the Hebrew University of Jerusalem. The Kaye Awards, now marking the tenth anniversary year of their inception, were presented on May 27 during the 66th meeting of the Hebrew University Board of Governors meeting in Jerusalem.

Bone loss possible after stomach reduction surgery

Women and men who have stomach reduction surgery to lose weight may be losing bone even when they take daily calcium supplements, putting them at risk for osteoporosis and bone fracture. These findings from a University of Pittsburgh study were presented Sunday in San Diego at the American Society of Nutritional Sciences program, part of the Experimental Biology 2003 meeting.

Bone marrow helps bones to repair themselves

Specially prepared titanium mesh and bone marrow cells have made it possible to allow new bone cells to grow in bone fractures. Researchers inserted a titanium mesh scaffold into a bone fracture in a rat. They allowed bone marrow cells to grow on this and the bone marrow cells stimulated new bone growth. In combination with bone marrow cells, titanium mesh forms a good culture medium for new bone growth in the case of bone damage. The researchers improved this bone growth by dynamically ‘sowing’ the cells onto the mesh.
