Sickle Cell Treatment Tested in Mice
(Ivanhoe Newswire) â Itâs just the beginning steps, but researchers say they have treated mice with human sickle-cell anemia disease successfully. Scientists accomplished this by using a process that reprogrammed the miceâs cells to an embryonic stem cell like state, without the use of eggs. This is the first proof in mice of using directly reprogrammed âinduced pluripotent stemâ (IPS) cells.
Sickle cell anemia is a disease of the blood marrow caused by a defect in a gene. The research was done in the lab of Whitehead Member Rudolf Jaenisch in Cambridge, Mass. Investigators started with cells from the skin of the diseased mice and after reprogramming them back into the embryonic stem cell like state, the cells were put back in the mice. The blood was then tested and the analysis showed the disease was corrected.
âThis demonstrates that IPS cells have the same potential for therapy as embryonic stem cells, without the ethical and practical issues raised in creating embryonic stem cells,â says lead study author Rudolph Jaenisch.
However, researchers caution that one challenge they must overcome is how to deliver the IPS cells to the body. Currently, there is no delivery system for humans.
