Lab-grown Kidneys Transplanted Into Rats 55
ananyo writes with this bit about lab grown organs from Nature: "Scientists at Massachusetts General Hospital in Boston have fitted rats with kidneys that were grown in a lab from stripped-down kidney scaffolds. When transplanted, these 'bioengineered' organs starting filtering the rodents' blood and making urine. The team, led by organ-regeneration specialist Harald Ott, started with the kidneys of recently deceased rats and used detergent to strip away the cells, leaving behind the underlying scaffold of connective tissues such as the structural components of blood vessels. They then regenerated the organ by seeding this scaffold with two cell types: human umbilical-vein cells to line the blood vessels, and kidney cells from newborn rats to produce the other tissues that make up the organ (paper)."

You don't need a lab. You can take half of someone's liver, put it in someone else, and both will grow and function.

But then have to deal with the rejection problems in the recipient. The promise of lab-grown ones is that you strip the donor's cells leaving only the scaffold thereby removing anything they would reject and seed it with the patient's own cells which they won't reject.
