Staining of embryos by project collaborators in Spain confirmed the existence of the cells with proteins derived from the jumping genes. (bath.ac.uk)
Co-lead author Professor Laurence Hurst, from the Milner Centre for Evolution at the University of Bath, said: "If a cell is damaged by the jumping genes - or any other sort of error such as having too few or too many chromosomes - then the embryo is better off removing these cells and not allowing them to become part of the developing baby. (bath.ac.uk)
Conversely, the single-cell data showed that the key cells that will become the embryo (the inner cell mass or ICM) don't contain jumping genes but instead express a virus-like gene called human endogenous virus H. This helps suppress the young jumping genes in the inner cell mass, fitting with an emerging pattern that we use our old genetic enemies to fight our new ones. (bath.ac.uk)
