Propidium 59-75 transformation related protein 53, pseudogene Mus musculus 201-204 9851850-4 1998 Propidium iodine staining revealed that the greatest reduction in apoptosis and the largest increase in cell numbers occurred in the tetraploid germ cell population of p53-/- mice. Propidium 0-16 transformation related protein 53, pseudogene Mus musculus 168-171
