tokens: Proerythroblasts and megakaryocytes massively accumulated in the spleens of the heterozygotes , and we showed that the neomycin resistance gene ( which is the positive selection marker in ES cells ) was expressed profusely in the abnormally abundant cells generated in the GATA-1 . 05 mutant females .
