Science Fiction Comes Alive as Researchers Grow Organs in Lab
1997 -- Charles Vacanti of University of Massachusetts Medical Center and Robert Langer of Massachusetts Institute of Technology report the growing of a cartilage structure – in the shape of a human ear – on a mouse’s back. 2008 -- Doris Taylor at the University of Minnesota and colleagues grow a beating rat heart in the lab. 2008 --Surgeons in Spain transplant a new windpipe into a patient. The organ is made from a cadaver windpipe stripped of its original cells and reseeded with the patient’s own cells. 2010 -- Researchers at Mass General Hospital grow a rat liver. 2010 -- Yale University scientists grow a functioning rat lung. 2010 -- Alex Seifalian in London transplants a lab-made tear duct into patient 2011 -- Dr. Seifalian makes a windpipe from nanocomposite materials plus a patient’s own stem cells; the new windpipe replaces the patient’s cancerous one, saving his life. In a separate procedure, an artery made at Dr. Seifalian’s lab is transplanted into a patient. 2012 -- Surgeons in Sweden transplant a major blood vessel into a 10-year-old girl. The vein was taken from a dead man, stripped of its tissue, then reseeded with the girl’s own cells. 2013 -- Scientists from Cornell University report the making of a human ear using living cartilage cells.
Just as Dante found it easier to conjure the pains of Hell than to evoke the joys of Heaven, so too do bioethicists find it easier to concoct the possible perils of a biotech-nanotech-infotech future than to appreciate how enhancements will contribute to flourishing lives. One of the chief goals of this symposium is to think about the indispensable role that virtue plays in human life. The chief motivating concern seems to be the fear that biotechnologies and other human enhancement technologies will somehow undermine human virtue. As we will see, far from undermining virtue, biotech, nanotech, and infotech enhancements will tend to support virtue; that is, they will help enable people to be actually good.
Bioculture critiques Cultural Critique Until literature departments take into account that humans are not just cultural or textual phenomena but something more complex, English and related disciplines will continue to be the laughingstock of the academic world that they have been for years because of their obscurantist dogmatism and their coddled and preening pseudo-radicalism. Until they listen to searching criticism of their doctrine, rather than dismissing it as the language of the devil, literature will continue to be betrayed in academe, and academic literary departments will continue to lose students and to isolate themselves from the intellectual advances of our time.
A British research team led by the world's leading heart surgeon has grown part of a human heart from stem cells for the first time.
For the first time, researchers have used adult bone marrow stem cells to regenerate healthy human liver tissue, according to a study published in the April issue of the journal Radiology.
"Molecular scientists . . . have developed a new procedure for the differentiation of human embryonic stem cells, with which they have created the first transplantable source of lung epithelial cells."
