Gene therapy converts dead bone graft to new, living tissue

...eplacing it with the only alternative available ?a donated section of comparable bone from a cadaver. The new splint of bone is then literally screwed into place, giving the patient most of the strength and support of the original bone. Bone, unlike any other tissue in the human body, can still perform one o...

Novel Therapy Tested in Mice Could Chase Away Cat Allergies

...Saxon and his colleagues first tested GFD in blood donated by people allergic to cats. They cultured blood cells with either GFD or with a purified human antibody as a control. Then they added the cat protein that triggers allergic reactions to all the blood cell cultures. “We measured more than 90 percent ...

Gene therapy promising for growing tooth-supporting bone

...ch leaves a second wound needing to heal, or using donated bone from a tissue bank, which yields unpredictable results. William Giannobile, professor of periodontics, prevention and geriatrics, led a team at the U-M School of Dentistry that delivered the gene encoding for bone morphogenetic protein-7 (BMP-7...

Double triumph in stem cell quest

...rocess: the 11 lines came from just 185 fresh eggs donated by 18 unpaid volunteers, meaning an average of only 17 eggs was needed per ESC line (Science, DOI: 10.1126/science.1112286). The donor "adult" cells came from patients aged 2 to 56, with a variety of conditions ranging from spinal injuries to an inh...

...they are interested in. The maize kernels will be donated to the U.S. Department of Agriculture's Maize Genetics Cooperative Stock Center, a national clearinghouse where scientists will be able to obtain the seeds for their experiments. "A good chunk of this project is developing a community resource," Bru...

Scientists succeed in cloning human embryos from eggs matured in the lab

Their results clearly show genetic modification of organisms by lateral transfer is a widespread natural phenomenon, and it can occur even between distantly related organisms, although particularly those wh...

Seal rookeries could provide a reliable food source for endangered California condors, study finds

... Newly released condors are fed stillborn calves donated by local cattle ranchers. Eventually, the birds supplement their diet with carcasses of deer, boar and other terrestrial wildlife they happen to find. Unfortunately, many of these animals are killed by hunters using lead shot, which is highly toxic t...
