A Method and Apparatus to Inactivate Stem Cell Nuclei
The development of a system to readily inactivate nuclei and nuclear chromosomes in stem cells will be of great value for scientists looking at stem cell biology. The invention proposed by UC researchers offers a unique approach to answer questions posed by experts in the field of stem cell research. The invention would allow for high cell throughput inactivation of nuclei and nuclear chromosomes in cells that are growing flat in a dish or unattached in suspension. This proposed technology will facilitate research in stem cell biology and provide scientists an investigative tool to facilitate the therapeutic use of stem cells.
Researchers at the University of California, Irvine in collaboration with scientists from the University of Massachusetts Medical School, are developing a method to remove or inactivate the nucleus of the human embryonic stem (hES) cell in the fused or pre-fused cell. Researchers are developing a system to differentiate between the stem cell and the somatic cell so that the stem cell nuclei can be inactivated. In effect, the cells can be irradiated with laser technology in several minutes, leaving a reasonably high number of cells that contain the cytoplasm of the stem cell but the programmed or to-be reprogrammed nucleus of the somatic cell. Prior to the development of this technique, there was no known way to enucleate cells without destroying the integrity of the cell (e.g. using a needle or using UV light which is generally damaging to the cell).
