Now scientists from The University of Manchester — part of the Manchester Cancer Research Centre — have measured the levels of the BCR - ABL genetic mutation in a cell model of CML.

Validating this original concept, we previously demonstrated that PGD - derived hES cells and their derivatives, which express the causal mutation implicated in the Myotonic Dystrophy type 1 (DM1), offer pertinent disease - cell models, applicable for a wide systemic mechanistic analysis ranging from functional studies at the cellular level to a large - scale drug screening.

The level of fluorescence you saw in the validation assay should give an accurate indication of how many pups will contain a mutation and many of the mice with the mutation will be homozygous for it in every cell; however, if the microinjection was done as the pronuclei were fusing, you may have several mosaic mice.

Prior studies by Bortvin and others showed that male germ cells quash the movement of transposons, minimizing mutations and ensuring high levels of sperm production.
