Save Japanese nuclear workers by collecting their stem cells

Banking stem cells could save Japan nuclear workers By Julie Steenhuysen CHICAGO   Apr 14, 2011  (Reuters) – Health officials should collect blood from workers at the crippled Fukushima Daiichi nuclear power plant in case they are accidentally exposed to high levels of radiation and need a stem cell transplant, Japanese researchers said on Thursday.

They said gathering blood from the workers would give them a ready source of their own stem cells that could help rebuild their bone marrow should they become exposed to high levels of radiation.

“The danger of a future accidental radiation exposure is not passed, since there has been a series of serious aftershocks even this April,” Dr Shuichi Taniguchi of Toranomon Hospital in Tokyo and Dr Tetsuya Tanimoto of the Japanese Foundation for Cancer Research wrote in the Lancet medical journal…..

The researchers say transplant teams are standing by in Japan and Europe to collect and store the nuclear workers’ cells, but so far the Nuclear Safety Commission of Japan is balking because it would cause a “physical and psychological burden for nuclear workers,” the team wrote.

Collecting cells from the workers has several advantages over donated cells, which require finding a matching donor and carry the risk of rejection.

Stem cell transplants from a person’s own cells would allow the workers to avoid taking drugs to suppress the immune system, helping them to better resist infections. The cells could quickly restore normal function to the body’s machinery for making blood cells.

And the workers’ cells could be banked and stored in case they develop leukemia, which could happen years down the road.

But the solution is not perfect, the team admits. High exposure to radiation would also attack cells in the gut, skin or lung — problems a stem cell transplant could not fix
