Cells taken from a person can be grown into blood vessels and reimplanted into the same person. This avoids immune rejection problems.
From a snippet of a patientís skin, researchers have grown blood vessels in a laboratory and then implanted them to restore blood flow around the patientís damaged arteries and veins.
It is the first time blood vessels created entirely from a patientís own tissues have been used for this purpose, the researchers report in the current issue of The New England Journal of Medicine.Cytograft Tissue Engineering of Novato, Calif., made the vessels, in a process that takes six to nine months.
The repair and replacement of worn out and broken parts is the future of medicine. The accumulation of techniques for replacing old parts will eventually lead to the halting and reversal of the aging process. This report is one step down the road toward full body rejuvenation.
If you read the full article above you'll learn that the first experimental subjects for a Novato California company were in Argentina - not exactly close by. I suspect this says something about medical regulation in America today. The Argentines were on hemodialysis for kidney failure and had what the report below characterized as "typical risk factors for end-stage renal disease". You might expect regulatory agencies to grant greater freedom of action to try out new treatments on people who are looking death in face. But this company used subjects from another country. I fear excessive regulatory obstacles in the way of new treatment development are costing lots of lives.
See the correspondence the experimenters sent to The New England Journal of Medicine entitled Tissue-Engineered Blood Vessel for Adult Arterial Revascularization.
