The concept of trying to quell the immune system attack on pancreas cells in diabetics goes back decades, but it has been beset by failure so far.
The cloned cells would be genetically identical to the patient's own, so they could replace part of an ailing brain or heart without touching off a full-scale attack from the patient's immune system.

It was an antibody that primes the immune system to attack and kill tumors.
Using the immune system to attack cancers is one of the most promising areas in cancer.
Seeing the innocuous virus, the immune system creates attack cells that should, in theory, fight off HIV.
Now others are working on a raft of vaccines that stimulate the immune system to attack cancerous prostate cells.
These proteins are highly-variable and thus difficult for the immune system to attack.
But like any vaccine, it triggers the immune system to attack an intruder, in this case, the cancerous cells.
One of the first to try to trigger the immune system to attack cancer was New York surgeon William Coley.
Designed to treat kidney cancer, TroVax works by encouraging the immune system to attack a protein found in solid cancers.
The vaccine, called Stimuvax, aims to stimulate the immune system to attack a protein fragment called MUC-1 found on lung, breast, prostate and colon tumors.

FORBES: Good News For Dendreon As Manufacturing Site Approved
Although the medicines work in different ways, all of them basically aim to do the same thing: to suppress the immune system, which appears in MS patients to attack the protective sheaths surrounding nerves.
FORBES: Biogen Prices New MS Pill At $55K, Prepares For Marketing Battle

Late in the summer ten kids with advanced neuroblastoma, one of the deadliest childhood cancers, began undergoing a radical new gene therapy with a breathtaking goal--to fight the disease not by deploying often inadequate chemotherapy and radiation but by jiggering the immune system to attack tumors it otherwise ignores.
Now into this gloom comes a new type of drug, called an anti-CD3 antibody, that aims for the first time to delay or prevent development of the devastating disease by arresting the immune system's attack on pancreatic islet cells.
Over the next decade animal studies at UCLA and elsewhere showed that macrophages are attracted to arteries when cholesterol lodged in the arteries gets chemically altered, or oxidized, so that the immune system suddenly spots it as foreign and goes on the attack.
In recent years, evidence has built that the immune system can sometimes attack and kill cancer cells--sometimes--but that cancer finds ways to fight back and evade or blunt the attack. (See "Cancer Miracles") For some people with advanced cancer, ipilimumab may be just enough to trigger a full-fledged anti-tumor attack.
In lupus the body's immune system turns on itself and produces "autoantibodies" that attack the joints, skin, kidneys, heart and brain.
