Finding organ donors could soon be a thing of the past. The latest miracle of modern medicine allowed doctors to replace a man’s cancerous windpipe with a new man-made one, comprised of a synthetic structure that was coated in the patient’s own stem cells.
According to a statement by Karolinska University Hospital, “Transplantations of tissue engineered windpipes with synthetic scaffolds in combination with the patient’s own stem cells as a standard procedure means that patients will not have to wait for a suitable donor organ,” reports AFP.
This is a huge leap forward for stem cell research. For starters, the stem cells were taken from the patient’s nose and bone marrow, which is much less morally controversial than embryonic stem cells (from unborn babies).
Also, a previous trachea (throat) stem cell transplant conducted by many of the same doctors had required a donor trachea to provide the structure for the stem cells. The process has since been streamlined.
“A windpipe can be made in between two days and a week, and because it uses the patient’s own cells, there’s no risk of organ rejection,” according to The Daily Beast.
Organ rejection is a serious risk that often requires strong medication to weaken the immune system (the system in charge of killing unwanted organisms in the body). Eliminating organ rejection risk will also eliminate the many risks from impairing one’s immune system, making many transplants much safer.
Stem cell research has come a long way towards improving medicine. It is still a nascent field, however.
“Experts say synthetic structures could be used to fashion simple organs like the windpipe, esophagus or bladder, but that it will be years before scientists can create more complicated organs like kidneys or hearts in the laboratory,” reports ABC News.

It is engaged in the discovery, development and commercialization of therapeutic products aimed at treating patients with severe and life-threatening disease states, including those in the therapeutic areas of hematology, nephrology (including transplant rejection), neurology, ophthalmology and cancer.
3. Dendreon Corp. (DNDN): Biotechnology industry with a market cap of $6.01B. It is focused on the discovery, development and commercialization of therapeutics that may improve cancer treatment options for patients. Its product portfolio includes active cellular immunotherapy and small molecule product candidates to treat a range of cancers.
4. PerkinElmer Inc. (PKI): Medical Instruments & Supplies industry with a market cap of $3.11B. It is a provider of technology, services and solutions to the diagnostics, research, environmental and safety, industrial and laboratory services markets. Its Human Health segment focuses on developing diagnostics, tools and applications to help detect diseases to accelerate the discovery and development of critical new therapies.
5. Ariad Pharmaceuticals Inc. (ARIA): Biotechnology industry with a market cap of $1.58B. It is focused on the discovery and development of drugs to provide therapeutic intervention in treating human diseases at the cellular level. Its lead cancer product candidate, ridaforolimus, is an internally discovered, potent inhibitor of the protein mTOR, which acts as a central regulator of protein synthesis, cell proliferation, cell cycle progression and cell survival. Blocking mTOR creates a starvation-like effect in cancer cells by interfering with cell growth, division, metabolism and angiogenesis.
