 Two recent studies by the University of California San Francisco and Stanford University have discovered evidence that stem cells from adult bone marrow do not have the same restorative qualities as embryonic stem cells.
These recent studies could bring new controversy to the already hot topic of stem cell research. These studies are in opposition to the idea that adult stem cells could be just as useful as embryonic stem cells. If the adult stem cells are not as useful as anticipated, the ban on usage of embryonic stem cells could become troublesome.
| San Francisco Gate wrote: | In both studies, the experimenters have been working with bone marrow from adult mice rather than embryos in order to learn whether -- as some scientists have claimed -- the adult marrow cells could differentiate into a wide variety of new cells that might be harvested to replace the damaged or destroyed cells that mark many diseases.
Instead of differentiating, however, the researchers found that the adult marrow cells fused with existing cells of the heart, liver and brain. Each fused cell contained two curiously distinct nuclei -- one from the original bone marrow cell and one from the cell with which the marrow cell had fused. |
The Stanford scientist have hope that marrow stem cells could potentially still help form new therapies for brain disorders.
