At the Toronto Centre for Phenogenomics Transgenic Core, we have implemented the use of KOSR+2i for the generation of chimeric mice using B6-derived ES cells available from the International Knockout Mouse Consortium (IKMC) repositories (see http://www.knockoutmouse.org for more information).
Differences in the rapid clearance of cells from the blood may reflect the number of B16F10 cells available for lung colonization in RNF13-KO mice.
To date, there are only two mouse mammary cancer cell lines commercially available that stably express the luc gene, 4 T1-luc2 and 4 T1-luc2-GFP cells, available from Caliper Life Sciences (Hopkinton, MA, USA).
The mice in the study were inoculated with human cells because mouse cells do not become infected with H.I.V.
Mouse cells have a history of not always being a good model for human cells.
Dr. Yamanaka worked with mouse cells, and Dr. Thomson worked with human cells from foreskins.
Last year, Dr. Yamanaka published a paper showing that he could add four genes to mouse cells and turn them into mouse embryonic stem cells.
Most were grown on mouse cells, and there is always a risk that mouse viruses could contaminate the cells and harm any human who receives them.
Another challenge was adapting the reprogramming method, which he first developed with mouse cells, to human cells.
The team found that the mouse cells contained resveratrol -- the original form of the compound.
