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.
The printing of an engineered [non-functional model of a] replacement kidney on stage at a recent TED talk is just the latest in a spate of recent high-profile biomedical engineering headlines. [more inside]
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."
The Pig Wings Project: "Rhetoric surrounding the development of new biological technologies make us wonder if pigs could fly one day. If pigs could fly, what shape their wings will take? The Pig Wings Project presents the first use of living pig tissue to construct and grow winged shape Semi-Living Objects."
