Another problem is getting viral vectors into bone-marrow stem cells, from which all of the blood's white cells are descended. Even when the rare stem cells are found, inserting genes into them is difficult because they divide infrequently, and the vectors used in gene therapy insert genes only into cells that are dividing. Had Anderson's group been able to use stem cells in the landmark therapy with little Ashanthi DeSilva, for example, follow-up treatments would not have been necessary. Endowed with the normal gene, the marrow stem cells would have produced a continuing supply...
...moving. Thrown from his horse at the third jump during a riding competition in Culpeper, Virginia, on Memorial Day last year, he became a "C1-C2"; the designation refers to a paralyzing injury to the area between the first and second cervical vertebrae, between the neck and the brain stem. It's called the "hangman's injury" because the C1-C2 break is what happens when the trapdoor opens and the noose snaps tight. He says, "It was as if I'd been hanged, cut down and sent to rehab...
...Jane was working within 1/16 of an inch of the brain stem. He placed a wire under both lamina--the bony covering of the spinal cord. He took bone from Reeve's hip and squeezed it down to get a solid fit between the C1 and C2. Then he put in a titanium pin the shape of a tiny croquet wicket and fused the sublaminal wire with the first and second vertebrae. Finally, he drilled holes in Reeve's skull and passed the wires through to get a solid fusion...

Two fine ones worth seeking out: Ska the Third Wave Vol. 2, with songs by such acts as Mock Turtle Soup, and Roots, Branch and Stem-Living Tradition in Ska!, featuring the Blue Beats and others...
