Swedes Implant Tissue-Engineered Vein in 10-Year-Old Girl

from the Los Angeles Times (Registration Required)

Swedish researchers have, for the first time, implanted a tissue-engineered vein made from her own stem cells into a 10-year-old girl. The implant of the portal vein had to be repeated after a year, but the team reported that the new vein dramatically improved the young girl's quality of life, allowing her to grow taller, gain weight and begin exercising.

The portal vein drains blood from the intestines and spleen to the liver, and blockages, which are usually genetic in origin, can cause serious medical complications such as enlarging the spleen and stunting growth. It can even be fatal. Normal treatment is to transplant a vein taken from the leg or the deep neck, but surgery to remove the vein can cause limb problems. The transplanted vein can also lead to loss of the liver and the need for an organ transplant.

Researchers have also been working with artificial veins made of Dacron or polytetrafluoroethylene, but have encountered problems with those as well. The synthetic grafts often fail, particularly if the vein is small.

PODCAST & VIDEO: 3D Printing Replacement Body Parts

Regenerative medicine, a fledgling field with the aim of regrowing parts from a person’s own cells, is being amplified with 3D-printing technology, which can now use organic materials to create scaffolds that cells need to grow into their final forms. Richard Wysk, a professor of industrial and systems engineering at North Carolina State University, discusses the latest successes with this research, and the timeline for creating more complicated structures.
